Well, without a detailed clinical evaluation it would be difficult to determine the cause of your symptoms. Possibilities that may need to be considered include middle ear infections/ inflammations, neuro-muscular causes such as muscle sprain, nerve impingement, injuries to muscles/ ligaments, inflammations, referred pain from other regions etc. I would suggest getting this evaluated by a primary care physician initially and depending on the cause diagnosed/ suspected, it can be managed accordingly or specialist care may be sought.
Hope this is helpful.
