Hi Jackie,
I have a similar problem with my vision...went through four prescription changes in one year only to later find out that I had Myasthenia Gravis. It depends on the day, the time of the day, the level of light, etc. Sometimes I need glasses and sometimes I don't. The vision in my right eye is much worse than the vision in my left eye.

My voice used to be very hoarse by the end of the day - people always asked me if I was sick. I started having difficulty swallowing too. I was always clearing my throat because it felt like there was something blocking my ability to swallow. By the end of a shopping trip I felt like I was walking through a swamp with weights on my legs.

It took a long time to get a diagnosis - my first problem was optic neuritis which is a common first symptom in MS - My primary doctor did the MG panel blood test and it came back positive... She referred me to a neurologist who later referred me to an specialist in MG. He undiagnosed me did a bunch of tests - thought maybe Lymes disease - then ALS - I went through the University and then on to Mayo Clinic in Rochester. They confirmed the original diagnosis of MG - but the whole process took 2 1/2 years - lots of med changes and tests. It is maddening and scary to wait for an answer when all you want to do is feelbetter.

I am glad you found us here and hope that you get answers soon.
