I am healthy enough to ride a bike three times a week and play golf, but the tinnitus comes and goes but like you i had mild symptoms from covid and that was three years ago. I am in two long haul covid clinics one in Cincinnati medical center where I live and one with Cleveland clinic I am going to the head doctor for the covid clinic this week when I am going to propose a regimen of steroids prednisone for a period of close to a month I will let you know how it goes because I saw a new ENT six months ago and when he put the camera up my nose he said to a colleague see that big blob and told me that my condition was totally fixable and it was in my head and not in my head like I was not imagining it, so after tendays of steroids and antibiotics i went back to him and had a CT scan he came in and you all better now whereas the blob of mucous was supposedly gone my ears were still clogged and now I believe it has come back again, so go figure.
