<s>[INST] Been having a toothache that goes from a sharp pain to feeling like Ive been punched in the jaw. The pain is or has been on my neck and  ear area and I have a huge knot on my neck almost behind my ear that looked like a big bump if you will aND I have messed with it bc I didnt think it was related at the time. I cant pinpoint one tooth that hurts and I go from being in extreme pain to just feeling like crap with a  low grade fever. I have a appointment with the dentist tomorrow but I dont know if theres anything she can do? Ive been taking some high antibiotics and its not getting better? [/INST] Hi Dear, Welcome to Chat Doctor. Understanding your concern. Thanks for your query. I have gone through your query. The symptoms you mention in your query indicates towards condition called BRUISE or grinding of teeth. Stress and anxiety are the most common factors responsible for it. It can lead to certain problems if left untreated like pain in ear, reduce in length of your teeth which further cause TMJ problem, headache and tenderness in muscles. I would suggest you to consult dentist for proper evaluation and rule out other causes like dental infection or ear infection. Your dentist may fit you with a night guard, which will protect your teeth during night, he/she may also prescribe you muscle relaxant .for now what you can do is avoid food and Chat Doctor. The knot in your neck occur may be due to peritonsilar abscess, strep throat and pharyngitis, consult ENT specialist (ear, nose , throat) for this. Hope your concern has been resolved. Get Well Soon.
