I finally gave in & tried it. I was pleasantly surprised. It is made of camphor & other natural oils. I tried looking for straight camphor, you used to be able to get it, but can't find anywhere. While it does stink, after 20 minutes, I guess you can shower, & it will still continue to work up to 8 hrs. I by no means am saying it's a miracle cure, or that it will work for everyone. I'm only saying for me, I felt a little better. It just seems to make the muscles feel more relaxed, I guess is how I'd phrase it . Although it's the connective tissue that actually hurts. Just thought I'd mention it in case someone wants to try it. I don't think Wal-Mart carries it, but they might be able to order. Not sure. Got mine @ a drug store. Hope this helps someone.
