Thank you for your comments and the article. Because of the carotid stenosis,
I felt sure there was some damage in the vestibular system. Just now starting research on possible neurological affects, so I expect the article to be quite helpful. The wait list to see neurologist here is 4 months. This all started with a kidney transplant in 2005 and skin cancers from the immunosuppressants showed up within 12 months. After almost 20 years, I am grateful for the health I have and access to first-class medical care. Thank you again for taking the time to reply.
