If my palms and soles feel burning but my test results are normal, what does 'deficiency heat type' mean?

Why do my palms and soles feel burning even though the test results are normal?

The reason your palms and soles may feel burning even when blood tests or diagnostic imaging at a hospital show 'normal' results is likely because the heat you are experiencing is not an 'actual rise in temperature' caused by inflammation or bacterial infection.

Test values in modern medicine primarily measure the levels of specific proteins, inflammatory markers, or the presence of physical tissue damage. However, the 'heat' we perceive does not simply mean that the temperature has risen.

The Gap Between Test Values and Perceived Temperature

When the internal balance of the body is disrupted, the brain or peripheral nerves may perceive a sensation of heat even if the actual body temperature is normal. In Korean medicine, this is examined from the perspective of 'Heoyeol' (deficiency heat).

Heoyeol refers to 'false heat' that feels relatively hot when energy is depleted and the body's internal regulatory ability has declined.

To use a simple analogy, it is similar to a car engine overheating due to a lack of coolant. It is not that the engine itself is defective, but rather that the energy (Yin-blood) capable of cooling the heat has become insufficient, leaving the body in a state where it easily overheats even with minor stimulation.

This deficiency-type heat exhibits the following characteristics:

• Often feeling hot on the surface but cold internally
• The sensation of heat does not easily subside even with rest
• Concentrated in specific areas (palms, soles, chest)

Ultimately, a normal test result is a reassuring sign that there is no organic disease, but it is also a signal that it is time to look beyond the numbers at 'energy balance' and 'functional decline'.

If you experience easy fatigue or poor sleep along with the sensation of heat, it may be a sign that your body's energy is depleted rather than a simple change in temperature.

Which type of heat sensation is closest to mine?

In Korean medicine, we do not simply say 'there is a fever'; we specifically categorize the nature of the heat based on its origin. Even without an apparent change in temperature, a disruption in internal balance can cause burning sensations in specific areas. The core operating principles determining this can be viewed in three main categories.

Yin deficiency with internal heat (陰虛內熱): deficiency heat caused by fluid deficiency.

This is a state where heat becomes relatively stronger as moisture and blood in the body, known as Jin-aek (body fluids), become insufficient. It is similar to an engine overheating due to a lack of coolant. In this case, a subtle sensation of heat is primarily felt in the palms, soles, or chest area,and symptoms may worsen as the night progresses, or may be accompanied by frequent dryness of the mouth and throat.

Giheo-balyeol (Qi Deficiency Heat): Heat due to declined regulatory ability

This is a state where the energy source, known as Gi (Qi), is insufficient, leading to a decreased ability to regulate or direct internal heat to the proper locations. Heat does not stay in one place but tends to float toward the surface. You may feel heat rising and falling mainly in the face or upper body, and you may easily become exhausted Cold sweatsor symptoms such as pain or shortness of breath may appear together.

Simhwa-wangseong (Hyperactive Heart Fire): Heat caused by psychological tension

This is a state where emotions such as excessive stress, tension, or anger are not resolved and accumulate in the heart in the form of heat. This is closer to a reaction to psychological stimuli than a physical deficiency.

Characteristics of the Simhwa-wangseong type

• A sudden feeling of heat rushing up to the face or upper chest
• Accompanied by chest tightness, anxiety, or sleep disorders
• A tendency for the tip of the tongue to become red or for inflammation to frequently occur inside the mouth

As such, the patterns of heat sensations go beyond a simple feeling of being 'hot'; the cause varies depending on whether it is due to a deficiency of bodily fluids, a decline in energy, or emotional distress. Therefore, it is important to closely observe where the burning sensation begins and in what situations it worsens.

How is the symptom of heat rising to the face different from a general fever?

There are two different natures of 'heat' that we commonly experience. It is important to understand the difference between a fever where the thermometer reading actually rises due to a cold or bacterial infection, and heat where the body temperature is normal but the individual feels hot.

First, 'excess heat' (Sil-yeol) is a state where there is actually an excess of heat energy in the body. The primary cause is an inflammatory response that occurs while fighting off external invaders (viruses, bacteria), and in this state, systemic fever may occur, accompanied by sweating or chills.

On the other hand, 'deficiency heat' (Heo-yeol) does not occur because there is actually too much heat, but rather a state where heat relatively rises because the bodily fluids or energy that act as 'coolant' to cool and regulate heat have become deficient.

Comparison of Characteristics: Excess Heat vs. Deficiency Heat

Category	Excess Heat (實熱)	Deficiency Heat (虛熱)
Pattern of Heat	Systemic fever, accompanied by high fever	Localized heat sensations in the face, hands, or feet
Test Indicators	Increased inflammatory markers, increased body temperature	Normal blood tests and body temperature
Body Condition	State of energy excess and conflict	Extreme fatigue, decreased vitality
Main Symptoms	Strong thirst, acute inflammation	Subtle burning sensation, cold sweats

The decisive difference between these two types of heat lies in the 'state of energy' felt when the heat occurs. In a state of excess heat, even if the body is hot, there is a strong feeling of energy colliding and reacting violently. Conversely, deficiency heat is a 'false heat' that occurs in a state of energy depletionwhich is more accurate.

Those experiencing deficiency heat often exhibit the following characteristics:

• The body feels heavy and fatigue does not go away despite having had sufficient rest.
• They may feel cold in areas other than where the heat sensation is felt (face, palms, soles of the feet).
• Symptoms tend to worsen after mental stress or overwork.

Ultimately, deficiency-heat symptoms should not be viewed as simply lowering the temperature, but from a perspective of replenishing depleted bodily fluids and restoring broken balance so that the heat subsides on its own.

Which of these more closely describes your usual physical condition?

Before an accurate diagnosis, it is necessary to carefully examine the physical reactions you usually feel. This is because the burning sensation in the palms and soles is not defined by the single sensation of being 'hot,' and its tendency varies depending on the accompanying secondary symptoms.

The following items are not definitive diagnostic tools, but reference indicators to gauge the direction of the imbalance currently occurring in your body. Please slowly check which characteristics of each type overlap most with your usual physical condition.

Checking Tendencies by Type

1. High possibility of Heat Type A state where there is an overall feeling of heat in the body and frequent dryness. You may often seek water due to a dry mouth or throat, and you may feel a lack of sleep or have difficulty falling into a deep sleep even after sufficient rest. Burning sensations in the palms and soles are the primary symptoms, and you frequently experience a feeling of heat surging throughout the body.

2. High possibility of Cold Type A state where the overall body temperature is low or the hands and feet are cold, but only specific areas (palms, soles, face) feel burning, showing a pattern of 'Upper-body heat and lower-body cold'. It is characterized by a strong feeling of chilliness in the lower abdomen or legs, while heat is concentrated only upward, making the temperature difference between the upper and lower body clearly felt.

3. High possibility of Mixed Type A case where the condition is not fixed and changes significantly depending on the time of day or situation. You may feel intense heat and burning during the day, but curl up due to chills at night, or show an irregular pattern where heat and cold sensations alternate depending on your physical condition.

This classification serves as basic data to understand where your body's energy is currently concentrated. Rather than looking for a fixed answer, please focus on reading the 'pattern' of the accompanying changes.

Please note these before your visit

• Physical sensations felt most frequently over the last 2 weeks (e.g., thirst, chilliness, alternating heat sensations)
• Specific times of day or specific situations when the heat sensation is most intense
• Whether temperature changes occur in other areas simultaneously with the burning sensation in the palms and soles

Could there be other medical causes?

Before approaching this from a Korean medicine perspective, there is a point we must address. It is the area of 'differential diagnosis'. Even if test results fall within the normal range, the possibility that it is the early stage of a specific disease or a functional imbalance that does not immediately appear in numerical values must not be excluded.

Medical Possibilities That Require Verification

The first area to examine is hormonal imbalance. In particular, hyperthyroidismendocrine disorders can excessively stimulate metabolism, causing a sensation of heat throughout the body or in specific areas. Since the mechanism of action differs from simple loss of energy or deficiency heat, precise verification of hormone levels through blood tests is necessary.

Issues with the nervous system and blood vessels must also be considered. Due to diabetes complications or vitamin deficiencies, Peripheral Neuropathysensory abnormalities in the fingertips and toes can occur, which are perceived as burning or tingling. Additionally, when there is an abnormality in the autonomic nervous system related to vasodilation, blood flow may concentrate in specific areas, leading to a sensation of heat.

Lastly, there is the possibility of side effects from medications currently being taken. Certain blood pressure medications, steroids, or specific antidepressant components can cause vasodilation, leading to facial flushing or heat in the hands and feet. If you have recently changed medications or started taking new supplements, this point should be carefully reviewed.

If the sensation of heat is accompanied by rapid weight loss, severe heart palpitations, or distinct skin rashes or ulcers, this may not be a simple functional imbalance, so an immediate detailed examination is recommended.

As shown, burning sensations in the palms and soles can manifest through very diverse pathways. An approach from the perspective of Korean medicine first verifies and excludes the possibility of such organic diseases,and only then does it demonstrate its true value when unexplained discomfort remains. To achieve safe and accurate improvement, an attitude of analyzing the cause from multiple perspectives is more important than anything else.

What are some supportive ways to manage the sensation of heat in daily life?

The burning sensation in the hands and feet felt in daily life is a kind of signal sent by the body. However, this sensation of heat often cannot be resolved simply by lowering the external temperature. Managing the heat through lifestyle habits is a supportive means to aid treatment, and more positive changes can be expected when combined with the process of correcting the fundamental imbalance.

Ways to Relieve Heat in Daily Life

First, rather than water that is too hot or too cold, a foot bath using lukewarm wateris recommended. This is not simply about washing the feet, but serves to draw energy down toward the lower body to disperse heat concentrated in the upper body and help the circulation of energy throughout the body.

Dietary management is also important. Consuming spicy, salty, irritating foods or caffeine can temporarily increase the heart rate and promote internal heat reactions, worsening the burning sensation. It is best to maintain a bland diet and create an environment that calms the body.

Above all, sufficient sleep and rest are key to alleviating deficiency heat. The time when the body's fluids are replenished and yin energy is restored occurs mainly during deep sleep. Lack of sleep weakens the body's cooling system, making it easy to feel heat even with small stimuli.

Lifestyle management is designed as a pillar to reduce heat stimuli and carry the changes from herbal medicine treatment into daily life.

If the sensation of heat persists despite improving lifestyle habits, or if you lose sleep because your hands and feet become hot every night, herbal medicine treatment determines the direction through pattern identification, whether to replenish deficient yin-blood or to release stagnant heat. We check the time when the heat subsides, the number of times you wake up, dry mouth, and changes in energy the following day.

Please note these before your visit

• Recent sleep duration and sleep quality (number of times waking up, etc.)
• Frequency of caffeine or irritating food intake
• Whether the sensation of heat temporarily decreases after a foot bath or rest

What behaviors should be avoided when the sensation of heat worsens?

When the burning sensation in the palms and soles worsens, we instinctively seek immediate cooling methods to eliminate the 'heat.' However, in the case of deficiency heat, the nature is different from general heat, so incorrect coping can actually cause the symptoms to become fixed or worsen.

Incorrect Coping Methods to Avoid

The most common mistake is relying on ice packs that are too cold or cold water friction. Forcing the skin surface temperature down may provide temporary cooling, but it causes blood vessels to constrict rapidly, hindering peripheral blood flow. Consequently, internal heat cannot be released smoothly and becomes trapped inside, which may lead to the adverse effect of heat rushing back more intensely after the cold compress is stopped.

Additionally, caution is needed when indiscriminately using antipyretics or sedatives to quickly suppress symptoms. Since deficiency heat (Heoyeol) is not inflammatory heat that raises the temperature on a thermometer, these medications cannot resolve the root cause and may instead diminish the body's natural regulatory ability.

Lastly, you should be wary of engaging in strenuous activities when in a state of deficiency heat caused by depleted bodily energy.

• Intense dieting: Extreme dietary restrictions further deplete Yin-blood (Eumhyeol), fueling deficiency heat.
• Excessive high-intensity exercise: Vigorous exercise that causes excessive sweating can dry up the body's fluids (Jin-aek), intensifying the sensation of heat.
• Excessive intake of caffeine and stimulants: Habits that overstimulate the central nervous system aggravate the sensation of heat rising to the upper body.

If you experience distinct skin color changes, decreased sensation, or numbness in specific areas beyond a simple feeling of heat, this may be a neurological issue rather than simple deficiency heat; therefore, an immediate and precise differential diagnosis is recommended.

Ultimately, the burning sensation caused by deficiency heat should not be forcibly suppressed or cooled down; instead, it is important to fill the deficiencies and create an environment where the body can manage heat on its own. Rather than coping based on common misconceptions, the priority should be a process of accurately determining if the heat in your body stems from a 'deficiency'.

What are the steps from the initial consultation to medical evaluation?

It is difficult to determine the exact nature of deficiency heat based solely on the feeling of being 'hot'. Only when the patient first observes and records their condition in detail can the identity of this invisible heat be more clearly pinpointed.

3-Step Flow for Efficient Diagnosis

1. Self-observation and organization: The first thing to do is objectively record the patterns of the heat sensation. Rather than simply stating 'it happens often,' please note specific details such as exactly what time of day the symptoms worsen, and whether the heat is in the center or the edges of the palms. It is especially important to check if the symptoms are concentrated at specific times, such as before falling asleep or in the early morning hours.

2. Understanding living environment and psychological state: In addition to physical symptoms, check your overall recent physical condition. Check if the quality of your sleep has dropped sharply or if you wake up frequently without falling into a deep sleep. Additionally, recording the intensity and duration of recent psychological stress will be a great help in understanding the mechanism by which deficiency heat occurs.

3. Precise confirmation through consultation: A final diagnosis is conducted at the Korean medicine clinic based on the recorded information. Through pulse diagnosis and medical interviews, the current state of bodily fluids and the flow of energy are examined, and a detailed analysis is performed on the 'depth of deficiency heat' originating from internal deficiencyrather than the heat sensation appearing on the surface.

Those who find it difficult to prepare before visiting the clinic may first undergo an initial medical interview through non-face-to-face consultation methods. If you provide a basic list of symptoms online or by phone first, a more focused consultation is possible during the in-person medical evaluation.

This step-by-step approach is a process where you take a proactive role in observing your own body. Only when your self-recorded data aligns with the results of the Korean medicine examination can we establish the appropriate direction to resolve your current discomfort.

What changes can be expected when deficiency heat symptoms improve?

The improvement of deficiency heat symptoms does not simply mean that the sensation of heat disappears. It is closer to a process of 'restoring systemic balance,' where depleted bodily fluids are replenished and floating heat returns to its proper place.

There is a difference between partial symptom relief and an overall change in the body's condition, as follows:

Category	Partial Symptom Relief (Temporary)	Systemic Balance Restoration (Expected Change)
Approach	External cooling or temporary soothing	Replenishing internal deficiencies and restoring heat regulation capacity
Perceived Change	Temporary decrease in heat in specific areas	Decrease in heat sensation along with an overall improvement in bodily condition
Sustainability	Possible recurrence depending on environment or bodily condition	Reinforcement of the body's own ability to manage heat

Changes leading to sleep and psychological stability

The first change you can expect is an improvement in the quality of sleep. For those who struggled to sleep because their palms and soles felt hot every night, as this heat sensation decreases, you may experience a shorter time to fall asleep and a deeper sleepexperience.

At the same time, as the heat sensation surging toward the face subsides, changes also appear in your psychological state. Feelings of chest tightness or irritability without a clear reason calm down, and a process of regaining emotional stability occurs simultaneously.

The correlation between energy recovery and deficiency heat

Deficiency heat is literally 'false heat.' When the body's vital energy (Jeong-gi) becomes deficient, heat relatively rises upward; when energy is recovered, the stagnation of deficiency heat naturally dissipates.

• Energy Reinforcement: As energy is recovered, the strength to maintain the body's center is developed.
• Relative Decrease in Heat Sensation: Once your overall energy is recharged, the apparent deficiency heat will gradually subside.
• Virtuous Cycle of Body Condition: As the feeling of heat decreases, sleep quality improves, which in turn leads to the recovery of vitality, creating a positive cycle.

Ultimately, the improvement of deficiency heat symptoms is not about extinguishing the heat, but a process of regaining the body's own 'capacity' to regulate temperature.

What is checked during the medical evaluation?

The ultimate goal of the medical consultation is to clearly identify the nature of the subjective heat you feel and determine which internal imbalance it stems from. Beyond the simple sensation of being hot, this is a process of establishing criteria to distinguish whether this heat is 'true heat' caused by excessive energy in the body, or 'false heat (deficiency heat)' occurring due to a lack of bodily fluids, which act as a coolant.

During the consultation, we carefully examine the following key elements to determine the nature of the heat sensation.

• Analysis of the Origin of Heat: We distinguish whether the current burning sensation is a state of Yin deficiency caused by the depletion of bodily fluids, or a state of stagnant heat where energy is not circulating properly and has become congested.
• Verification of General Body Indicators: We comprehensively examine the efficiency of your usual digestive function, the patterns and frequency of bowel movements and urination, and the quality of your sleep to gauge the overall metabolic state and water retention capacity of your body.
• Identification of Triggers and Cycles: We analyze whether the heat sensation worsens at specific times (e.g., at night) or appears after psychological tension or the consumption of specific foods to set the direction for improvement.

This multifaceted verification process is not simply about suppressing symptoms, but a time to understand why your body is unable to regulate heat. Information collected through in-person visits or, if necessary, remote consultations serves as the decisive basis for diagnosing your current condition.

Diagnostic Goals Reached Through Consultation

Ultimately, at the end of the consultation, we find the answer to 'where the heat in my body comes from, and what needs to be replenished or removed.' This will serve as a concrete milestone to resolve vague anxiety and establish a management direction suitable for your condition.
