yes... I have a hard time with them as well!! Before IVIG, not only could I barely stand up that long, hold my hands to my head (my muscles would burn SOOO badly with fatigue), much less shave my legs/or hold my razor.. but the heat really did me in.. I'd have to lay on the floor right out of the shower for about 15 minutes or so, I just felt melted.. now with IVIG i'm much better, but still feel pretty weak after a shower if it's too warm especially! I can also blow dry my hair now (I couldn't even comb my hair by myself before IVIG)..
