Hello, for years I have tinnitus and a little hearing loss on my left ear due to a firecracker. I could live with it until forteen days ago I got another hearing loss (again in the left ear), can hear my pulse in this ear AND everytime I make noises I get some sort of feedback "piing" (lower frequency then my tinnitus). I try not to speak because it gets worse when I speak or make noise. My doctor made hearing tests (left ear: bad, right ear: very good) cleaned my ears, took blood (OK), arranged a head MRI (OK) and now gave me cortison, SO far nothing really helped. I also have an appointment for an cardiologist to check my vessels - but I really don't think that this will cre the feedback sound which is extremely annoying for me.
