I suspect that i had covid-19 in march 2020 before anyone was doing testing for it. i came down with ringing in the ear in april '20 and it has been with me for almost one year. saw my pcp, ent, then another ent and nobody can figure it out, annoying?

Tinnitus, or ringing in the ear, can be caused by many things. It can be caused by COVID-19 so if you haven’t had a test recently, perhaps you should-just to rule it out. It can also be caused by hearing loss so if ENT didn’t find anything, see an audiologist and have a hearing test. Treating the hearing loss, if present, can be helpful. And, the audiologist can offer treatment for the tinnitus.

I agree with Dr. Ferranti . Additionally, if you are not finding improvement with conventional treatment approaches - auricular and scalp acupuncture can sometimes be helpful even if etiology is poorly defined.

I knew a physician who had chronic tinnitus and travelled far and wide looking for an effective treatment. He was unsuccessful as there is none unless an otolaryngologist can find a cause that's treatable. I think Dr. Fowler's suggestion may be worth a try, though.
