They can last for many, many months at a time, with constant pain and weird feelings in
the ears everyday. The symptoms disappear on their own, only to return at a later
date, usually a year or two later.
I am experiencing a bout of this now, and it is driving me crazy since I do not know how to relieve the symptoms, or how long they will take to go away. It makes it difficult to concentrate and can bring on depression because of the length of time it lasts.
