It’s interesting prednisone in relation to tinnitus, when I was initially diagnosed with myasthenia my neurologist noted I had a bad reaction and told me never to take it again, they discovered a clotting disorder and I had manic symptoms very unlike me. Years later I had a hemorrhagic stroke, they had me on prednisone for nine months despite the warnings. After that hospital release and becoming conscious the tinnitus started and has been present, over ten years. When I have colds or allergies it’s worse, but so bothersome all the time. No one seems to have answer or help. It’s very real and I worry as it is certainly brain-related.
