Hi Abby,

Medically, I have no idea....but

I was dx'd with lymphedema a couple of years before MG. It was so bad I went for decongestive therapy (barbaric..but it worked) for 3 months.

Anyway, my neuro said I would see a difference with the fluid build up once I was on Mestinon for a few months. Said the lymphatics are supported by muscles...weak muscles = weak lymphatics.

Have no idea if medical literature has documented this - but I can tell you for me - it has been a true observation.

So maybe your IVIG helped in this way..or maybe it was something totally unrelated. But I'm glad your knee has improved so much!
