Nicky,

This is great!

My experiences are similar to yours, although I can't do to much aerobic exercises for some reason, I have noticed that exercise does seem to help my MG.

I think it does have something to do with blood flow. My worst days are the days when I sit around a lot or if I work too much at doing any one thing. My best days are when I mix in small amounts of exercise with relaxation between.

Thanks.
