Well we just got back from the ENT doctor, I can never pronounce or spell the fancy name for them. They did a thorough hearing test which could indicate fluid behind the eardrum and she has no fluid and was told she had excellent hearing for age 62. Probably because she did not attend lost of rock concerts as a teenager like I did.
He did a very thorough doctor patient talk asking lots of questions and did more nuero muscular tests. His diagnosis was she may have an inner ear viral infection which is hard to treat and can take a week or months to fully clear up. He prescribed an anti viral drug and also an anti shingles drug because she had chicken pox as a child and one outbreak of shingles 35 years ago, he saw some small bumps in one ear canal that could be a type of shingles that effects the ear. Also a very small dose of Valium to control dizziness.
So we will wait and see. She can't drive until the severe dizzyness gets better so I will do the driving like I did in Wales and Australia and South Africa!
