Hi welcome to Health care magic forum.
Thanks for asking a question to H.C.M.F.
Your mother had cerebral atrophy
, and un bearable ear pain
due to infection of the internal ear.
Your mother is under the treatment of a neurologist
for cerebral atrophy. It is a permanent change with no way for complete relief.And she is using medicines for maintenance.
Now she has got ear pain due to infection of the internal ear. That is to be treated completely .
So i advise you to consult an E.N.T.surgeon for diagnosis and treatment. he will give treatment for medical treatment, if no relief he may propose mastoidectomy
, with advise of the neurologist. There is a possibility of complete relief.
Wishing for a quick and complete recovery.
