I still have tinnitus - started six months ago with an ear infection. My Synthroid dose has been increased to 100 mcg. Most of my hypo symptoms are gone, or at least, lessened. Except the tinnitus (in fact, it seems to have increased some). I believe my tinnitus is connected to my hypothyroidism (doctor, of course, does not). So, has anyone “out there” found an answer?
