I better say something since this seems to be catching on. The methyl salicylate in icy hot can be fatal with excessive applications. It has happened with an athlete who made constant use of muscle rub, though more often it happens in small children.

Oh dear god, I just had the anxiety attack of the century after reading your post! I had just put on more MR than I usually do and I only weigh 49kg. I'm definitely going to use it more sparingly now.

Although you should've heard the lady from the crisis line I called, she seemed to think it was really funny that I thought I was going to die from muscle rub...
