I hadn't realized this at all. Is this true for all of the stick on patches, no matter what brand? I haven't yet tried the patch you gave me (and thank you! I'm waiting for menstrual cramps to hit to use it) but I'd probably be pretty inactive while it was on. If I need to be walking around and such for it to get really hot I'll save it for when I'm going out and about.
Ya know, I read over the ThermaCare site a while back and I don't remember that they said anything about this aspect of how they work. That sure would have been good info to tell people at their site - for heaven's sake!
