Thanks for taking time to hear me out... my friend's wife had a hysterectomy a year and a half ago. Over this period of time, she has experienced loss of balance and a 'cloud' over her eyes. She was treated for atypical migraines, and as time went on high doses of steroids were the only treatment that seemed to help and allowed her to have daily life functions. Over the last week, doctors thought it was vasculitis, but an angiogram has proved this diagnosis to be negative. Currently she is unresponsive are there any auto-immune diseases that you would think might be a possibility?
