Most tongue pain is caused by ulceration of the mucous membrane at the tip of the tongue or inflammation of the tongue papillae. You can apply topical painkillers such as lidocaine gel, compound benzocaine gel and bendamycin spray for pain relief; anti-inflammatory drugs such as chlorhexidine gargle, chlorhexidine hydrochloride gargle and cetiolide tablets to suppress inflammation; and drugs such as oral ulcer dispersion, ice borax and epidermal growth factor gel to promote wound healing. However, if there is no relief or further aggravation after medication, promptly visit a hospital to clarify the specific cause of the tongue pain and seek further treatment under the guidance of a doctor.
