I have had low level tinnitus for 4 yrs.(Hissing with high pitch ring) Audio test revealed, very little hearing loss at high level. About 2 months ago my tinnitus spiked to high levels with intermittent ear pain mainly left ear. I noticed because I am an Red wine drinking enthusiast, that when I over served myself my tinnitus completely goes away for about 24 to 36 hours then returns with a vengeance from hell for about 4 or 5 days then returns to very low levels. I tried this several times to try establish a pattern and it exists. ?? is what is the science behind this. MY ENT and Audiologist offer no answer.
