Just found this site. Am 53, and had a ringing in left ear since Apr this year (2015). So far doctor gave me steroid spray for the tubes, and antibiotics for possible middle ear infection. Initially the ringing seemed to vary in volume, but pretty much constant now, combination of hiss and very high pitched tone. Is there any hope for an improvement ? My doctor is MOST unsympathetic, not sure what I should be insisting on?
