Tinnitus since a year. Is it stroke?

I recently had brain mri it showed "Thick mucus in b/l ethmoid air cells". Can this be causing my tinnitus? I have earache not that I feel it generall but if i put earbuds(i dnt use it though, just to check this soreness i did try), the left affected ear feels gives me tingling pain inside the ear canal when slightly touched, it doesn't happen in right ear though. And i have 2/10 tinnitus in right ear( recently developed ) and left one is majorly affected. One ent ruled it as RTM but recently another ENT put me on a course of steroid nasal drops, camphor and another med. i have already been on a course of medrol, absolut 3g, nerverich, renerve plus etc. Absolut 3g somehow manages the tinnitus but i get rashes and too many side effects even spleen pain as well. I had audiometry, its fine no hearing loss. But sometimes randomly a high pitch sound takes place (random ear, but mostly in left), which then subsides in some seconds. Is it stroke? I am scared! Please help me n explain this ;(
