A burning sensation in your hands usually signals irritated or damaged nerves, and stopping it depends on identifying what’s driving the problem. For quick relief, cooling your hands under tepid running water (around 15°C or 59°F) for up to 20 minutes can calm the sensation by stabilizing the cells that release inflammatory chemicals in your skin. But lasting relief requires addressing the underlying cause, which ranges from vitamin deficiencies to diabetes to nerve compression.
What Causes Burning in the Hands
The most common cause is peripheral neuropathy, a condition where the small nerve fibers in your hands or feet become damaged and start sending pain signals they shouldn’t. Diabetes is the single most frequent trigger. High blood sugar gradually damages nerve fibers over months or years, and the hands and feet are typically the first places you feel it because those nerves are the longest and most vulnerable.
Other conditions that cause the same burning include carpal tunnel syndrome (where a compressed nerve in the wrist creates burning, tingling, or numbness), autoimmune diseases like rheumatoid arthritis or lupus, infections, and exposure to certain toxins. A less well-known cause is vitamin B12 deficiency. When B12 drops below about 200 pg/mL in the blood, neurological symptoms can appear. One documented case showed a patient with tingling and burning in the hands at a B12 level of just 104 pg/mL, roughly half the threshold for deficiency.
There’s also a rarer vascular condition called erythromelalgia, where blood vessels in the hands or feet suddenly dilate, causing intense burning, redness, and warmth. Flares are typically triggered by heat exposure, exercise, stress, alcohol, spicy food, or caffeine. If your burning episodes come with visible redness and are clearly tied to warming up, this is worth raising with your doctor.
Why Damaged Nerves Feel Like Burning
When nerve fibers are injured, whether from high blood sugar, compression, or inflammation, the damage triggers a chain reaction. Immune cells in the nervous system become activated and release inflammatory molecules that make pain-sensing nerve endings hypersensitive. Essentially, the volume knob on your pain signals gets turned up. Nerves that would normally transmit mild sensations start firing as though they’re detecting intense heat, which is why you feel burning even when nothing hot is touching your skin.
In chronic cases, the protective coating around nerve fibers (myelin) can break down, further distorting signals. This is why burning from neuropathy tends to get worse over time if the root cause isn’t treated. The nerves aren’t just misfiring temporarily; they’re physically deteriorating.
Immediate Relief at Home
When burning flares up, running cool (not ice-cold) water over your hands is the most effective immediate step. Tepid water at around 15°C works best. Keep your hands under the stream for up to 20 minutes. This reduces pain by stabilizing mast cells, which are the immune cells that release histamine and drive inflammation in the skin. It also reduces swelling. Avoid ice or ice water, which causes intense blood vessel constriction and can actually make things worse.
Cooling gels designed for burns can also help in the short term. Simply covering the affected area after cooling provides additional pain relief. If your burning tends to flare at night, keeping your hands elevated and uncovered by heavy blankets may reduce the intensity.
For erythromelalgia-related burning specifically, avoiding known triggers makes a significant difference. That means limiting caffeine, alcohol, and spicy foods, staying hydrated, keeping rooms cool, and managing stress. Many people with this condition keep a fan nearby or use cooling cloths during flares.
Treating the Underlying Cause
If diabetes is behind your nerve damage, bringing blood sugar under control is the single most important thing you can do. There’s no universal target number that works for everyone. Guidelines from both the American Diabetes Association and the UK’s NICE recommend individualized goals set with your doctor, because pushing blood sugar too low too fast can actually trigger a painful condition sometimes called “insulin neuritis,” a temporary worsening of nerve pain. The goal is steady, sustainable blood sugar control rather than dramatic swings.
If B12 deficiency is the cause, supplementation can reverse symptoms, sometimes completely, especially when caught early. Your doctor can check your level with a simple blood test. Deficiency is more common than many people realize, particularly in vegetarians, older adults, and anyone taking long-term acid-reducing medications.
For carpal tunnel syndrome, the treatment path usually starts with wrist splinting (especially at night), ergonomic adjustments to how you use your hands, and in some cases a procedure to relieve pressure on the nerve.
Medications for Nerve Pain
When the burning persists despite treating the underlying condition, medications that calm overactive nerve signaling are the standard approach. The two main categories are certain antidepressants and certain anti-seizure medications, both of which work by dampening the way nerves transmit pain signals.
Among antidepressants, older tricyclic types are considered the most effective for nerve pain, though they come with side effects like dry mouth, constipation, and dizziness, and doses are typically kept modest to avoid heart-related risks. A newer option in the same family works differently on brain chemistry and is simpler to dose, with nausea as the most common side effect. Starting at a lower dose for the first week usually helps your body adjust.
Anti-seizure medications that target calcium channels in nerves are the other first-line choice. These reduce the excitability of damaged nerves, which directly addresses the “volume turned up” problem described earlier. Drowsiness and dizziness are the most common side effects.
Topical Options
If you prefer to avoid oral medications, or want something to use alongside them, topical treatments applied directly to the hands can help. Lidocaine patches (5% concentration) numb the area and are applied directly over the painful spot. A higher-intensity option is a capsaicin patch (8% concentration), which works by overwhelming and then desensitizing the pain receptors in your skin. The capsaicin patch is applied for 60 minutes in a clinical setting, typically repeated every 12 weeks. It requires a numbing cream beforehand because the initial application itself causes intense burning before the desensitizing effect kicks in.
When Burning Hands Need Urgent Attention
Burning in the hands alone is rarely an emergency, but certain combinations of symptoms change that picture. If the burning comes on suddenly along with weakness on one side of your body, difficulty speaking, facial drooping, or confusion, treat it as a potential stroke and call emergency services. If burning is accompanied by a rapidly spreading rash, swelling of the throat or face, or difficulty breathing, that suggests a severe allergic reaction.
Burning that starts suddenly in both hands and feet and rapidly worsens over days, especially after a recent illness, can indicate Guillain-Barré syndrome, a condition where the immune system attacks the nerves. This requires immediate medical evaluation. Similarly, if you notice your hands turning pale or blue alongside the burning, that points to a vascular problem that needs prompt assessment to rule out blood flow obstruction.
