Direct Answer
A burning sensation on the skin usually has one of three sources: a dermatologic cause (contact dermatitis, sunburn, allergic reaction), a neurologic cause (peripheral or small-fiber neuropathy, nerve compression, post-herpetic neuralgia, MS), or a systemic cause (fibromyalgia, diabetes, autoimmune disease). Sudden onset with weakness, facial droop, or breathing difficulty is an emergency. Persistent, unexplained, or one-sided burning warrants evaluation by a dermatologist and/or neurologist.
What causes a burning sensation on your skin?
Burning skin is a symptom, not a diagnosis. The same sensation can come from inflamed skin (dermatologic), irritated nerves (neurologic), or systemic disease affecting both. Physicians sort causes by the pattern: is there a visible rash? Is it one-sided or symmetric? Is it triggered by temperature, touch, or stress?
Dermatological causes
- Contact dermatitis — burning, redness, and itching from an allergen or irritant (nickel, fragrance, soap, plant exposure)
- Eczema (atopic dermatitis) — chronic dry, inflamed skin with flares
- Sunburn or chemical burn — visible erythema with a clear exposure history
- Urticaria / allergic reaction — burning with hives, may progress to anaphylaxis
- Rosacea or perioral dermatitis — facial burning and flushing
Neurological causes
When the skin looks normal but burns, the source is often in the nerves. Peripheral neuropathy typically starts in the feet and hands. Small fiber neuropathy produces burning, tingling, and temperature sensitivity, sometimes without findings on standard nerve conduction studies. Nerve compression (sciatica, meralgia paresthetica) produces burning in the territory of a specific nerve. Multiple sclerosis can present with burning, numbness, or band-like sensations.
Systemic causes
- Diabetes-related neuropathy — symmetric, stocking-glove burning; one of the most common causes
- Shingles and post-herpetic neuralgia — band of burning in a single dermatome, often before the rash appears
- Fibromyalgia — widespread burning, tenderness, and fatigue
- Autoimmune disease (lupus, Sjögren's) — burning skin or mucosal symptoms
- Vitamin B12 or thyroid deficiency — reversible neuropathy when treated
When is burning skin an emergency?
- Sudden burning with one-sided weakness, facial droop, or trouble speaking — call 911 (possible stroke)
- Burning with hives, swelling of the lips/tongue, or trouble breathing — anaphylaxis, call 911
- Chemical exposure with progressive burning or skin damage — emergency care
- Band of burning followed by a rash on one side of the body — likely shingles; see a physician within 72 hours for antiviral treatment
Diagnosis and testing
A dermatologist will examine the skin and may perform patch testing or a skin biopsy. A neurologist may order nerve conduction studies, EMG, MRI, or a small-fiber skin biopsy. Bloodwork commonly includes glucose/HbA1c, thyroid panel, vitamin B12, autoimmune markers, and metabolic panels. A clear history (timing, triggers, distribution) does most of the diagnostic work.
Treatment options
Dermatologic causes respond to topical steroids, antihistamines, barrier repair, and trigger avoidance. Neurologic burning is often treated with gabapentin, pregabalin, duloxetine, or topical lidocaine and capsaicin. Systemic causes require treating the underlying disease — glycemic control in diabetes, antivirals in shingles, hormone replacement when indicated. Persistent or unexplained burning belongs with a specialist.

Frequently Asked Questions
Why does my skin feel like it's burning but nothing is there?
When the skin looks normal but burns, the most common explanation is a small-fiber or peripheral neuropathy — the nerves carrying sensation are irritated or damaged. Causes include diabetes, vitamin deficiencies, autoimmune disease, post-herpetic neuralgia, and idiopathic small fiber neuropathy. A neurologist can evaluate with focused testing.
Can anxiety cause burning skin sensations?
Yes. Anxiety and panic states can amplify or trigger paresthesias — including burning, tingling, and crawling skin sensations — through autonomic activation and heightened sensory awareness. However, anxiety should be a diagnosis of exclusion: rule out neurologic, dermatologic, and systemic causes first, especially when symptoms are persistent, one-sided, or progressive.
Is burning skin a sign of nerve damage?
It can be. Burning, tingling, and temperature sensitivity are hallmark symptoms of small-fiber and peripheral neuropathy. Other nerve-related causes include post-herpetic neuralgia, nerve compression, and central nervous system disease like MS. Nerve damage is one of several possibilities; only an exam and targeted testing can distinguish them.
When should I see a doctor about burning skin?
See a physician if the burning is persistent (more than a few days), progressive, one-sided, follows a band on the body, occurs with weakness or numbness, or interferes with sleep or daily life. Call 911 for sudden burning with stroke symptoms or for any signs of anaphylaxis.
What specialist treats burning skin sensations?
Start with a dermatologist if the skin looks abnormal or there is a rash. Start with a neurologist if the skin looks normal but burns, tingles, or has temperature sensitivity. A primary-care or internal-medicine physician can coordinate referrals and order initial labs.
