Hey Marty,
Awhile ago Melodi posted a link to some gel slippers you can put in the freezer or you can just run cold water over your feet or maybe a bag of frozen peas. The heat makes me miserable too, fortunately we aren't having a hot summer yet, but when we do I'm going to be in the house trying to stay cool.
Something weird is going on with me now, I'm experiencing leg muscle weakness in both legs all the way up to my hips, but only in the evening. My next neuro appt is 3 months away so I guess if this persists I'll try to bump it up. Very creepy, it's like I almost have to drag my legs......who knows whats around the corner with this condition??
