That all sounds good, @rose4622, I'm glad that your Medicare is covering your PT.
I had vestibular therapy for my balance/vertigo and I remember that the eye exercises made things worse before they got better. At that time I was still working full time and would always have to schedule the eye exercises at the end of the day, so I wouldn't be sick/dizzy during the work day.
After a while, though, everything got much better.
