Hi all. This is my first post. I have been experienced double vision that gets worse at the end of the day and when I'm tired. No other symptoms. Two eye doctors sent my home saying there was "nothing wrong" with me. Went to neurologist, who ordered many tests. MRI had no plaques, so MS was ruled out. (I think he did that just to be safe). He suspects myasthenia. Does anyone know what else could cause this with zero other symptoms?

If it is MG, how likely is it to become general rather than ocular?

Thanks.
