Hi Laura, and interesting question!

I had my first attack in the summertime, don't remember which month...June or July. According to my MS nurse practicioner, I had one in February 2008, although I'm not so sure. My symptoms are bad now, in winter, but they most certainly get worse in the summer! Heat and the bad humidity we get here really does a number on me! But extreme cold, even if I am only exposed for a minute, will cause at least one limb or appendage to go completely numb for hours or days.
