I used this stuff today because capsaicin is supposed to be an effective help with arthritis pain. Anybody ever tried this? It is made from hot peppers. The insert sheet says don't go out in the sun. Let me tell you, don't go out and mow the yard in long pants hours after you've applied it, even if the sun isn't shining...and especially don't come in a take a lukewarm shower. OMGosh, my legs have been burning for over an hour. The sensation is just beginning to subside. The instructions say the burning will go away after a few days. I guess your skin becomes acclimated to it....I'm not sure if I'll last that long.
