<s>[INST] Ive had a bad tooth abscess, tooth was enventually pulled after three courses of antibiotics difficult extraction, which has left me with numb chin lip with nerve pain running through it also ringing in my ear !! X-ray done today showed a shadow which the dentist mentioned could poss be a cyst! Could the cyst be causing the nerve pain ? And is there any medication to relieve the nerve pain ? [/INST] Thanks for your query, I have gone through your query. The pain can be because of the nerve injury while removing the tooth or by the pressure applied over the nerve by the cyst. It can be a cyst. The other possible cause can be a neuralgia following extraction. Nothing to be panic, consult an oral physician and get it evaluated. If it is a nerve injury it can be treated with nerve regenerating Chat Doctor.  If it is a neuralgia, then it can be treated with carbamazepine. I hope my answer will help you, take care. </s>
