Hello all..I've had some form if tinnitus on and off for many years, however it always quickly subsided. 10 days ago I awoke from a short nap with terrible loud hissing heartbeat pulsating tinnitus, stronger on the left side but pretty much all over up my head. It has been nonstop since. I cannot eat, sleep or barely function. I can increase the volume by moving my jaw, pressing my scalp, etc. Did have an MRI during the week it was actually for another condition, non- diabetes neuropathy in my feet. The MRI was clean except for arthritis in my neck. I am so sick and tired and getting more depressed each day. Can anybody give me guidance who to see first beyond my GP he has not been a lot of help? An ERT specialist perhaps? Amazes me so many sufferers of this and not enough being done to cure it. appreciate any support and advice..
