A burning sensation in the palm usually traces back to nerve irritation, whether from compression at the wrist, damage to tiny nerve fibers in the skin, or a systemic condition like diabetes that affects nerves throughout the body. Less often, the cause is a skin disorder, a vascular condition, or a medication side effect. Because “burning palm” is a symptom rather than a diagnosis, the underlying reason matters enormously for treatment, and the range of possibilities is wider than most people expect.
Nerve Compression at the Wrist
The most familiar cause of burning, tingling, or numbness in the palm is compression of a nerve as it passes through a tight tunnel in the wrist. Two structures are responsible for the vast majority of these cases.
Carpal tunnel syndrome occurs when the median nerve gets squeezed inside the carpal tunnel, a narrow passageway on the palm side of the wrist formed by bones and a tough band of tissue. The median nerve supplies sensation to the thumb, index finger, middle finger, and part of the ring finger, so burning or tingling in those areas, especially at night or after repetitive hand use, is a hallmark. Electrodiagnostic tests can confirm the diagnosis with high accuracy. In patients who have had symptoms for more than six months and do not have diabetes, comparative nerve conduction studies can reach a positive predictive value of 100 percent when two tests agree.1MDPI. Diagnostic Accuracy of Electrodiagnostic Comparative Latency Studies of Carpal Tunnel Syndrome: Single Test and Concordance Between Multiple Tests For people with diabetes, especially those over 60, diagnostic accuracy drops because diabetes itself can alter nerve conduction, making the picture muddier.
Guyon’s canal syndrome is less well known but can also produce a burning palm. Guyon’s canal sits on the pinky side of the wrist, and the ulnar nerve runs through it. When something compresses the nerve there, the burning and numbness tend to affect the little finger and the outer half of the ring finger. One reported case involved a 35-year-old sawyer who had burning pain and numbness along exactly that distribution for three months before imaging revealed a fatty tumor inside Guyon’s canal.2PubMed Central. Guyon’s canal resulting from lipoma: A case report and review of the literature Causes range from ganglion cysts and lipomas to repetitive pressure from tools or cycling handlebars.
A practical clue for telling these apart at home: if the burning is worst in the thumb, index, and middle fingers and wakes you up at night, think carpal tunnel. If it is concentrated in the pinky and ring finger, think ulnar nerve. Either way, a doctor can sort it out with a physical exam and, if needed, nerve conduction testing.
Small Fiber Neuropathy
When the burning is more diffuse and not clearly limited to one nerve’s territory, small fiber neuropathy is a strong possibility. This condition damages the tiny nerve endings in the skin that detect pain and temperature. It is increasingly recognized as a major cause of burning pain in the hands and feet, especially in older adults.3Cleveland Clinic Journal of Medicine. Small fiber neuropathy: A burning problem The sensation often starts in the feet and climbs upward over months or years, eventually reaching the palms. Because the affected fibers are too small to show up on standard nerve conduction studies, this type of neuropathy can be missed by routine testing. A skin biopsy that counts intraepidermal nerve fiber density is one of the more reliable ways to confirm it.3Cleveland Clinic Journal of Medicine. Small fiber neuropathy: A burning problem
Diabetes is the most common identifiable cause, but impaired glucose tolerance, even before full diabetes develops, can be enough to damage these small fibers. Components of metabolic syndrome such as high triglycerides, high blood pressure, and central obesity have also been linked. In some people no cause is ever found, a frustrating situation called idiopathic small fiber neuropathy. Diabetic distal symmetric polyneuropathy specifically can produce burning in both the palms and soles in a symmetric, stocking-glove pattern.4Pain Neurosurgery. Painful Diabetic Neuropathy
Nutritional Deficiencies and Toxins
Peripheral nerves are vulnerable to damage from a surprisingly wide range of nutritional imbalances and environmental exposures.5PubMed Central. Peripheral neuropathy due to vitamin deficiency, toxins, and medications Vitamin B12 deficiency is probably the best known culprit. It tends to produce burning and tingling in the hands and feet, sometimes alongside balance problems and cognitive changes. People who follow strict vegan diets, take long-term acid-suppressing medications, or have autoimmune conditions affecting the stomach are at heightened risk. Vitamin B6 is unusual in that both deficiency and excess can cause neuropathy; people who take high-dose B6 supplements for months sometimes develop burning hands and feet from too much of it.
Alcohol is another common offender. Chronic heavy drinking damages nerves through a combination of direct toxicity and nutritional depletion, particularly of thiamine (vitamin B1). Certain industrial chemicals and heavy metals can do the same. The typical pattern is a length-dependent neuropathy, meaning the longest nerves get hit first, so the feet burn before the hands. But by the time someone notices palmar symptoms, the damage has often been building for a while.
Skin Conditions That Burn
Not every burning palm involves nerve damage. Several skin conditions can produce intense burning that is easy to confuse with a neurological problem.
Contact Dermatitis and Capsaicin Exposure
If you have been handling hot peppers, the explanation may be straightforward. Capsaicin, the chemical that gives chili peppers their heat, activates pain receptors on nerve fibers in the skin, producing a burning sensation that can be severe enough to mimic a chemical burn or allergic reaction. This has been given its own informal name: Hunan hand syndrome.6Saudi Journal of Emergency Medicine. Hunan hand syndrome: benign capsaicininduced contact dermatitis presenting with alarming symptoms The condition is self-limited and resolves once the capsaicin is washed away or metabolized, but it can be alarming while it lasts. Wearing gloves while cutting peppers prevents it entirely.
Other irritant or allergic contact dermatitis can produce similar burning on the palms. Common triggers include cleaning products, solvents, latex gloves, certain metals, and fragrances. The palms are thick-skinned and relatively resistant compared to the back of the hand, but prolonged or repeated exposure can break down that barrier.
Dyshidrotic Eczema
Dyshidrotic eczema, sometimes called pompholyx, produces intensely itchy and burning deep-seated blisters along the edges of the fingers and across the palms. The blisters are small, filled with clear fluid, and often appear in clusters. One case report described a 42-year-old woman with a rash on her left palm accompanied by intense itching, oozing, and a burning sensation.7AYUSHDHARA. A Case Study on Pompholyx (Dyshidrotic Eczema) w.s.r. to Vicharchika The condition can also be triggered by medications; there is a documented case of dyshidrotic eczema developing on the palms three days after intravenous immunoglobulin therapy, with deep-seated vesicles and intense burning.8PubMed Central. Dyshidrotic Eczema following Intravenous Immunoglobulin Therapy in Guillain-Barré Syndrome: A Case Report Stress, seasonal allergies, and exposure to certain metals like nickel are common triggers. Flares tend to come and go, and the itching-burning combination often makes it hard to leave the hands alone.
Erythromelalgia
If your palms burn, turn red, and feel hot to the touch, especially in warm environments, erythromelalgia may be the cause. This uncommon vascular condition is defined by a triad of intense burning pain, warmth, and redness, primarily in the hands and feet.9PubMed Central. Pediatric erythromelalgia from multidisciplinary perspectives: a scoping review Symptoms are typically worsened by heat and relieved by cold, which leads many people to repeatedly soak their hands in cold water or hold ice packs, a pattern that can itself cause skin damage over time.10PubMed Central. Primary Erythromelalgia: Historical Perspective and Current Update
Primary erythromelalgia can run in families and involves mutations in sodium channels in pain-sensing nerves. Secondary erythromelalgia occurs alongside other conditions, most commonly blood disorders like polycythemia vera. Diagnosis is largely clinical, based on the characteristic appearance and symptom pattern, but it can take years to get the right label because the episodes may not be happening during a doctor’s visit. If you notice that your palms flare red and burn specifically in response to warmth, mention this pattern explicitly.
Chemotherapy and Hand-Foot Syndrome
People undergoing chemotherapy sometimes develop a distinct reaction called hand-foot syndrome, also known as palmar-plantar erythrodysesthesia. It is a common side effect of certain drugs, characterized by redness, swelling, and burning on the palms and soles.11PubMed Central. Do you know this syndrome? Hand-foot syndrome Early symptoms include tingling, discomfort, and redness that may progress to blistering and even ulceration in severe cases.12PubMed. Pegylated liposomal doxorubicin-induced hand-foot syndrome in a patient with breast cancer: Case report and FAERS database analysis
Capecitabine, fluorouracil, and pegylated liposomal doxorubicin are among the drugs most frequently associated with it. One case involved a 65-year-old woman with breast cancer on capecitabine who developed fissuring and bleeding on her palms and soles with a progressive burning sensation.13International Journal of Research in Dermatology. Hand and foot syndrome secondary to capecitabine The severity is dose-dependent, and management often involves dose reduction, emollients, and topical treatments. If you are on chemotherapy and your palms start burning, your oncology team needs to know promptly because catching it early allows for dose adjustments before the skin breaks down further.
Complex Regional Pain Syndrome
After an injury, surgery, or fracture involving the hand or wrist, a small percentage of people develop pain that far exceeds what the original injury should produce. Complex regional pain syndrome is a debilitating condition in which the nervous system essentially overreacts, generating burning pain, swelling, color changes, temperature changes, and motor problems in the affected limb.14PubMed Central. Modern Management of Complex Regional Pain Syndrome: A Practical Evidence-Based Review for Hand and Upper Extremity Surgeons The burning can be continuous or triggered by light touch, and the palm may appear shiny, mottled, or swollen.
CRPS is diagnosed clinically based on the combination of symptoms and the disproportionate nature of the pain relative to the inciting event. Early recognition matters because treatment is more effective when started promptly. Physical therapy, nerve blocks, and certain medications can help, but delayed diagnosis sometimes allows the condition to become entrenched.
Liver Disease and Palmar Erythema
A persistently red, warm, and sometimes burning palm can be a sign of liver cirrhosis. Palmar erythema, a redness concentrated on the fleshy parts of the palm near the thumb and little finger, is a recognized skin manifestation of chronic liver disease.15PubMed Central. Skin Changes in Cirrhosis It results from changes in blood flow and hormone metabolism that come with liver dysfunction. The redness may be accompanied by warmth and a mild burning feeling, though it is not always painful.
Palmar erythema is not exclusive to liver disease. It also occurs during pregnancy, with rheumatoid arthritis, with thyroid disorders, and sometimes in perfectly healthy individuals. But when it appears alongside other signs like spider angiomas on the chest, unexplained fatigue, or abdominal swelling, it should prompt a conversation with your doctor about liver function testing.
Post-Stroke Pain and Central Causes
Burning in the palm does not always originate in the hand or the nerves that supply it. Central post-stroke pain is a neuropathic pain syndrome that can develop after a stroke, producing burning, shooting, or electric shock-like sensations in areas of the body affected by the stroke.16Romanian Journal of Neurology. Radiological and clinical biomarkers in patients with central post stroke pain If the stroke damaged parts of the brain involved in processing sensation from the hand, the palm can burn even though there is nothing wrong with the hand itself. The pain can appear weeks to months after the stroke and is often difficult to treat because conventional pain medications targeting peripheral nerves may not work well against centrally generated pain.
Multiple sclerosis and other conditions affecting the spinal cord or brain can produce similar centrally driven burning sensations. The distinguishing feature is that the burning does not follow the territory of a single peripheral nerve and may come with other neurological symptoms like weakness or changes in coordination.
Infections and Post-Infectious Pain
Herpes zoster, the reactivation of the chickenpox virus, can cause burning pain along a strip of skin supplied by a single nerve root. While the trunk is the most common location, zoster can affect the hand if the virus reactivates in a cervical nerve root. One case described a 57-year-old woman who presented with localized pain, vesicles, fever, and a burning sensation along cervical and thoracic dermatomes.17International Journal of AYUSH Case Reports. Ayurvedic Management of Herpes Zoster with Post-Herpetic Neuralgia: A Case Report After the blisters resolve, some people develop post-herpetic neuralgia, a persistent burning or stabbing pain in the same area that can last months or years.
The risk of post-herpetic neuralgia increases with age, which is one reason the shingles vaccine is recommended for older adults. If burning palm pain appeared after a blistering rash in the same area, post-herpetic neuralgia is a likely explanation.
Cold Injury and Environmental Exposure
Prolonged exposure to cold, wet conditions can damage the nerves and blood vessels in the hands and feet even without actual freezing. This is called nonfreezing cold injury, historically known as trench foot when it affects the feet. The injury passes through stages: cold exposure, a post-exposure phase, a hyperemic phase with increased blood flow and burning pain, and a long-term phase that can include persistent pain and abnormal sensation.18PubMed Central. Nonfreezing Cold Injury (Trench Foot) Most patients report losing feeling for at least 30 minutes during the cold exposure, followed by pain or abnormal sensation when rewarming begins. The burning phase can persist for weeks or months.
This is more common in outdoor workers, military personnel, and people experiencing homelessness. The hands are less frequently affected than the feet because people tend to protect their hands more consciously, but extended exposure to wet, cold conditions without gloves can produce the same injury. Treatment options are limited, though amitriptyline appears to be the most effective medication for the chronic pain that sometimes follows.18PubMed Central. Nonfreezing Cold Injury (Trench Foot)
When to See a Doctor
A one-time burning sensation after handling peppers or a new cleaning product usually needs nothing more than thorough hand washing. But burning that keeps coming back, wakes you at night, or is accompanied by visible changes like redness, swelling, blistering, or skin color changes deserves medical attention. Burning that appears after starting a new medication, especially chemotherapy, should be reported to the prescribing team right away.
Some red flags warrant more urgent evaluation. Burning accompanied by sudden weakness or grip loss could suggest acute nerve compression requiring prompt treatment. Burning that starts after a hand or wrist injury and seems wildly out of proportion to the injury itself should raise concern for CRPS, where early intervention makes a real difference in outcomes. Burning in both palms and feet that is steadily worsening over weeks or months points toward a systemic cause like diabetes or a nutritional deficiency that may be treatable once identified. And burning that follows a shingles-like rash has a clear explanation but may need specific pain management.
The wide range of possible causes means that the single most useful thing you can bring to a doctor’s appointment is a clear description of the pattern: where exactly it burns, when it started, what makes it better or worse, whether it is constant or comes and goes, and whether anything else changed around the same time, whether that is a new medication, an injury, a dietary shift, or a cold exposure. That kind of detail narrows the list faster than any single test can.
