Tinnitus, sore jaw from grinding all night, hearing impairment. What's wrong with me?

2 things wrong. You have symptoms of temporomandibular joint inflammation. You should eat soft food that doesnt put stress on jaw joint. Dont chew gum, dont chew ice, etc. Anti-inflammatiory meds klike Aleve (naproxen) help. Heat helps. See your dentist. Often a splint can be made to prevent grinding. Hearing loss is likely unrelated. You need to be seen by ENT for hearing test and evaluation.
