What sensations may occur?

Numbness starting from the toes, burning sensations, searing pain, or loss of sensation may occur. These may be more uncomfortable at night or appear similarly in both feet.

Why should I check my feet every day?

If you cannot feel pain and temperature well, you may miss small wounds and burns. You should check for skin color changes, blisters, cracks, and swelling, and avoid walking barefoot or using strong heat packs.

Which medical evaluation takes priority?

Blood glucose levels, neurological evaluation, and the condition of blood vessels and foot wounds must be checked. If there are sudden color changes or signs of infection, you must receive a prompt medical evaluation.

How does Korean medicine treatment proceed?

While maintaining diabetes treatment and foot care, test results and current medications are shared. The scope in which Korean medicine treatment can help with remaining pain, coldness, or sleep discomfort is then determined.

Why foot sensation is checked separately when diabetes is present

Diabetic peripheral neuropathy often begins at the toes and leads to numbness, burning, and decreased sensation in both feet, but patterns vary by person. Even if pain is not severe, you may not feel temperature or wounds well; therefore, the fact that it "does not hurt" alone is not enough to determine that the feet are safe.

Commonly confused terms and their differences: A diagnosis of diabetic neuropathy is not confirmed based solely on the feeling that the feet are hot or cold. Causes that create similar sensations, such as vascular issues, nerve issues originating from the lower back, vitamin deficiencies, and thyroid disease, are distinguished through medical history, neurological examination, and tests.
Information to record before your visit: Under the same lighting every day, check for blisters, cracks, redness, and swelling on the soles and between the toes, and record where the numbness begins and if it worsens at night. Please also provide your blood glucose records, recent HbA1c levels, current medications, and any areas chafed by shoes during your evaluation.
Scope of this material: NIDDK data was applied to the symptoms of diabetic peripheral neuropathy and foot safety checks. This explanation is not a criterion for diagnosing the cause of foot heat as diabetes or for directly selecting supplements or painkillers; if wounds, black discoloration, or infection are visible, you must notify medical staff immediately.

Heat and Cold ColumnIf there is heat in the soles of the feet, is it diabetes? Causes to consider when blood glucose is normal

When you experience burning sensations in the soles of your feet without a diabetes diagnosis, we explain the difference between blood glucose tests and neuropathy tests, check for thyroid issues, vitamin B12 deficiency, or nerve compression, and describe the direction of Korean herbal medicine and acupuncture treatments.

Heat and Cold ColumnBurning sensations in the soles of the feet with diabetes: neuropathy, foot condition, and Korean medicine treatment

We categorize the burning sensation in the soles of the feet for diabetes patients into peripheral neuropathy, wounds, or blood flow issues, and explain Korean herbal medicine and acupuncture treatments to manage nighttime burning and sleep while maintaining diabetes medication.

Heat and Cold ColumnKorean medicine treatment for cold feet in diabetes: distinguishing between cold sensation and sensory loss

This explains how cold feet in people with diabetes are categorized into actual cold sensation, peripheral nerve sensory changes, or blood flow issues, and describes Korean herbal medicine and acupuncture treatments based on Spleen-Yang deficiency, Kidney-Yang deficiency, or Qi and Blood deficiency.

Medical GuideHow do I distinguish between different types of heat and burning sensations in the soles of the feet or palms of the hands?

Heat in the palms and soles may be centered on a burning sensation rather than actual skin temperature. We first distinguish whether there is numbness or decreased sensation; if the cause is not clear from tests, we determine the direction of Korean medicine treatment by examining whether it worsens at night and its relation to sleep, dry mouth, and fatigue.

Medical GuideWhen my hands and feet are cold and chilly, should I only think of it as cold hypersensitivity (Sujok Naengjeung)?

Symptoms of cold hands and feet vary, even under the single term 'cold hypersensitivity' (sujok-naengjeung). By distinguishing between color changes, differences between sides, numbness, and general fatigue, and by examining digestion, sleep, and lower abdominal coldness when tests show no clear cause, we can determine if Korean medicine treatment is appropriate.

Comparison of similar terms

Conditions requiring differential diagnosisPeripheral Neuropathy

Peripheral neuropathy can cause numbness, sensory loss, and burning sensations in the hands and feet. If the burning sensation in the soles persists or sensation becomes dull, do not dismiss it as a constitutional issue; you must have it confirmed at a medical institution.

Symptom ExpressionParesthesia

Sensory abnormalities can make your hands or feet feel as if they are burning or freezing, even without an actual change in temperature. If you experience numbness or decreased sensation along with feelings of heat or cold, it is necessary to distinguish whether the cause is nerve-related.

Symptom ExpressionBurning sensation

A burning sensation is a term that describes a stronger, more painful sensation than a simple feeling of warmth. Since causes vary, including nerve issues, inflammation, skin lesions, or oral diseases, we check the affected area, any loss of sensation, and visible changes together.

Medical TerminologyDifferential Diagnosis

Differential diagnosis is the process of distinguishing possible causes one by one through examination, testing, and monitoring progress, rather than determining a disease name based on a single symptom. This is the first and most necessary step for both sensations of heat and cold.
