Not sure what normal is for MG since I hear it's a snowflake disease and therefore everyone is different. . .but for me, when I was undiagnosed and without medication I was so bad off I was in a wheelchair because I was unable to walk or hold my weight at all when the disease hit the legs. And years later, after a remission, when I went into crisis but was finally put on some medication (mestinon and prednisone), I still needed a walker but never got so bad as to need the chair again. It wasn't until I was on all the correct meds (IVIG) and got strong enough that I was able to walk unassisted. For me, it was all med-related.

I hope that helps, debra
