Burning sensation: what’s behind that sudden heat or sting?
A burning sensation can be tiny and annoying or a red flag for something serious. Where you feel it—feet, chest, throat, mouth, skin or belly—tells a lot about the cause. Below are straightforward reasons, practical fixes you can try now, and clear signs you should see a clinician.
Common causes and what they feel like
Nerve problems often cause a persistent burning, tingling or electric shock feeling. Diabetes and some chemotherapy drugs can damage nerves and bring on neuropathy. If you’re taking chemo like capecitabine, watch for new numbness or burning in hands and feet.
Acid reflux and heartburn usually give a burning behind the breastbone or a sour taste in the throat. If meals, bending, or lying down make it worse, reflux is likely. Some meds that affect stomach acid—like famotidine alternatives or stopping proton-pump inhibitors—can change symptoms, so medication changes matter.
Skin irritation from contact, sunburn, or topical products creates hot, painful skin that’s local and visible. Drugs like Accutane can make skin more sensitive and prone to burning after sun exposure. Infections—yeast or bacterial—can also cause burning in a concentrated spot (mouth, groin, or urinary tract).
Simple first-aid and home steps
If it’s a minor skin burn or irritation, cool the area with clean water and avoid creams that sting. For hot, burning feet from friction or neuropathy, loosen tight shoes, use cushioned socks, and apply a fragrance-free moisturizer.
For heartburn, try an antacid, sit upright after eating, and avoid spicy or fatty meals. If a new medication started around the same time as the burning, keep a list and talk to your prescriber—sometimes switching or adjusting dose fixes the issue.
Topical pain creams like low-dose capsaicin can help nerve pain but often cause an initial burning before they stop nerve signals. Use as directed and stop if the reaction worsens.
If a baby shows mouth or face burning while teething, use chilled teething rings rather than gels with strong anesthetics; infants are sensitive and need gentle care.
When the burning is tied to an antibiotic or other prescription (for example, digestive upset from certain antibiotics), read the medication guide and ask a pharmacist about side effects. Our article on "Duricef Antibiotic: Uses, Effectiveness, Dosage & Side Effects" covers common reactions worth checking.
Urgent signs to act on: sudden severe burning with weakness, slurred speech, chest pain, high fever, blood in urine, or quick spread of skin redness. These need immediate medical attention.

Keep a short symptom diary—what triggers it, when it started, and what makes it better or worse—to help your provider diagnose faster.
Burning sensations are common, and many are treatable. When in doubt, document what you feel and ask for help—especially if symptoms start fast or get worse.
