Whirlwind (& Erin), Swelling of the eyelids is NOT a symptom of MG. If you are specifically talking about the eyelids themselves having tissue inflammation, then it is probably an allergic response. It could be autoimmune if you had something like lupus or arthritis.

Whirlwind, What you should be doing is calling/seeing your primary doc or allergist right away. If you at all suspect that you may have an allergy to Mestinon, then you should stop taking it. Call your neuro, since he is the one who prescribed the drug, and tell him about it!!!

DO NOT WAIT. If you are having an allergic reaction, I don't think I have to tell you that it could get worse. You've had enough experience with allergies, right?

Erin, If you do have real swelling, then you need to talk to your doctor. It could be from your Prednisone. Have you had a sleep apnea test?

Symptoms like this need attention right away . . . and not from this forum!!! Sorry to be so blunt, but you need to seek out medical care when things like this happen.
