I use to be an exercise fanatic..lol and now it is hard. I got a new exercise bike for my birthday but when I exercise my legs gets too weak. I exercised one day and my legs got so tight and weak. Yesterday (walk video) I exercised and my legs got tight, painful and could not walk right. Today I just moved around the house and my walking and muscles are a little better. Are your jaw muscles messed up from MS? Today I was setting on the porch, watching the kids play and my right eye started hurting. My right eye is the one I have had blurred and double vision in. My left side of my body is weaker than my right but when I have eye problems it is in my right eye..go fiqure. though I have had vision changes in both eyes.
