Please can anyone tell me if you have a middle ear problem such as an abnormal tymp test, can that cause constant rumbling low tones non stop? No high pitches or ringing either. I can't find an answer anywhere. What if one ear is stiffer than the other on the test? I don't have any issue with my right ear, no T -nothing. I don't know where to turn and I can't sleep for three months now.( Just a couple of hours a night.) Two ENTs , oral surgeon, neurologist, spine dr and primary care dr. And suffering with scary sounds all night. All I want to know is can middle ear stiffness cause this or just give up now? Please help me deal.....I keep crying from sheer exhaustion. I fear Losing not only my mind but my 20 year career. Thanks.
