why do my lips burn
Lip burning sensation may also result from different types of lip burns or even chapped lips. Certain types of neuropathy (nerve problems) may result in lip burning sensation, as the cranial nerves from the brain supply the lips. Symptoms may occur in the lips alone or any other area of the body that is supplied by a peripheral nerve. Lip burning sensation may be the only symptom experienced, it may start as a tingling (paresthesia) and change to numbness, or there may be a combination of symptoms. Burns from heat, cold, chemicals and sun may also cause a lip burning sensation.
