(i'm not confirmed with a diagnosis, just get ivig).. but my symptoms are always there, but fluctuate with all those same things, and heat-a hot shower will turn me into a big lump of jello.. and hormones make it all worse too - for about three days.. I will be freaked out that I can't swallow anything without choking for days.. and then get my IVIG and It's hard to imagine ever having a hard time! so weird
