I have low pitch rumbling in my right ear. MRI was useless. Hearing test "perfect". Its hard to sleep without background noise. I think its a damaged blood vessel in my brain or neck: veinous stenosis.

It could well be that. An MRA and MRV could confirm or rule out those suspicions. If the damaged vessel can be found, it might be treatable by stenting.
