If I had tinnitus, I'd go see an otolaryngologist immediately and likely will not take too seriously anything anybody has to say on an internet pilot's board, including myself, even though I had a very successful career in science before becoming a lawyer. The medical research I did was in the auditory system in general and childhood total deafness in particular.
The etiology of tinnitus is not crystal clear, but the most common causes are age related hearing loss and exposure to loud noises. The human's inner hair cells are so delicate that any damage to them can result in tinnitus. One of the medical residents also told me that he once saw someone with tinnitus, but it was because the guy never cleaned his ears and the ear canal was impacted with cerumen. You know, earwax.
Please go see your doctor. Ask to be examined by a board certified otolaryngologist. Sorry I cannot give anyone a ringing (no pun intended) endorsement. Good luck.
