手足麻木
Numbness in the hands and feet is a symptom that cannot be explained by a single cause alone. From peripheral neuropathy to burning sensations in the soles of the feet and Raynaud's syndrome: we provide guidance on the underlying conditions causing numbness.
What to check first
We identify when the symptoms began, situations that worsen them, and any accompanying discomfort.
What to distinguish together
We narrow down the possibilities by comparing similar-looking conditions with previous test results.
What to look for on this page
We provide guidance on major patterns, differential criteria, and the sequence of confirmation during the medical evaluation.
Korean medicine diagnosis looks at a different layer than hospital tests: it is not superior, but a different perspective.
Key information at a glance
- Since numbness in the hands and feet has multiple causes, we categorize them by underlying condition
- This leads to guidance on conditions that cause numbness, such as peripheral nerves, circulation, and the spine
Overview
Hands and feetnumbnessfeet numbness is a symptom that cannot be explained by a single cause alone. Even if the sensation of numbness is the same, the underlying mechanisms differ, such as cases of nerve damage, excessive vascular constriction, or cases where changes in sensory nerves appear not as numbness but burning sensationas something else.
In Korean medicine, numbness in the extremities is viewed Qi and Blood(氣血as a state where Qi and Blood do not circulate evenly to the ends. Since the fingertips and toes are farthest from the heart and the hardest places for Qi and Blood to reach, numbness serves as a signal that the flow of circulation or sensation is blocked somewhere. Therefore, the first step is to categorize 'where the blockage is'.
Causes to check along with numbness
Accompanying symptoms that appear along with numbness serve as clues to narrow down the cause.
If numbness occurs as sensation becomes dull → Peripheral neuropathy
If numbness begins symmetrically from the tips of the hands and feet following diabetes or a chronic illness, we first examine the category of peripheral neuropathy, where changes to the nerves themselves are the underlying cause.
If burning or heat sensations accompany the numbness → Heat in soles/palms
If burning and flushing sensations are more prominent than numbness and worsen at night, we examine heat in the soles/palms, where changes in sensory nerves are perceived as heat.
If numbness occurs with color changes in the cold → Raynaud's syndrome
If the hands and feet turn pale, blue, and then red in response to cold or stress along with numbness, we first examine Raynaud's syndrome, which involves vascular spasms.
If it is difficult to distinguish which one you have, it is helpful to note the area where the numbness began and any accompanying sensations (decreased sensation, burning, color changes) to verify during your medical evaluation.
When the types of numbness are categorized this way, common assumptions about numbness may be seen differently.
Common Misconceptions
"Numbness in the hands and feet is always a blood circulation problem"
While circulation is one cause, the backgrounds are diverse, ranging from nerve changes (peripheral neuropathy) and sensory nerve changes perceived as heat (heat in soles), to vascular spasms (Raynaud's). Different causes require different approaches.
"I just leave the numbness alone because it's due to age"
While aging can be the background, there may be hidden causes that require management, such as diabetes or nutritional deficiencies. It is safer to identify the cause if the numbness spreads or if sensation significantly decreases.
"It's not a disease because it goes away if I massage or shake my limbs"
Temporary improvement is different from the absence of a cause. If it recurs and is accompanied by other symptoms (decreased sensation, color changes, burning), it is advisable to check which condition it most closely resembles.
If you have narrowed down which background it most closely resembles, you can find more detailed information on the corresponding cause in the related diseases guide below.
Frequently Asked Questions about Numbness in Hands and Feet
Is numbness in the hands and feet always a nerve problem?
Nerve damage (peripheral neuropathy) is a common cause, but not the only one. Causes vary, including vascular circulation issues (Raynaud's syndrome) and cases where sensory nerve changes are felt as heat (heat in soles), so accompanying symptoms must be examined together.
From the perspective of heat and cold, this is viewed as a process where the temperature imbalance between the upper and lower body accumulates.
- Accumulation of causes for upper and lower body temperature regulation issues
- The body's regulatory functions cannot keep up
- This is seen as manifesting as symptoms such as upper-body heat and lower-body cold
The process of verification during medical evaluation
Now, we verify when and how your symptoms change
Since the way discomfort manifests can differ even within the same diagnosis, we review existing test results alongside the progression of symptoms.
Pattern Identification (Byeon-jeung)
Symptoms are verified in detail through pulse diagnosis and medical interview
Through pulse diagnosis and patient consultation, we identify the tendency toward upper-body heat and lower-body cold and the accompanying patterns, and then explain the approach best suited to the current condition.
The prescription direction is determined, and changes after administration are verified
Based on the findings from the medical interview and examination, the prescription direction is explained, and the same director oversees everything from preparation to the changes after administration.
Medical and Content Review Baekrokdam's medical standards
For numbness in hands and feet, we listen to the progression before the name
We identify when heat in the upper body and coldness in the extremities alternate, and examine the timing in relation to sleep, digestion, and stress. Since the way the body generates and distributes heat varies even for the same diagnosis, we link the patterns identified through pulse diagnosis, tongue diagnosis, and patient interviews to the herbal medicine prescription and the monitoring of progress.
"For discomfort that cannot be explained by test results alone, we trace back through the symptoms starting from when they first began."

Before Your Consultation
Please make a note of the times when the temperature differs between the upper and lower body, changes in throbbing, sweating, digestion, and sleep, as well as any previous test results.
During Your First Visit
Rather than concluding with a single symptom name, we categorize the onset, aggravating factors, and accompanying symptoms based on the patterns of cold and heat.
Once Treatment Begins
Prescriptions are adjusted based not only on the intensity of discomfort but also on the frequency, recovery time, and changes observed in your daily life.
