I had been having a lot of pain in my lower back. We were at the beach walking around the Blue Crab Festival...the more I walked around the more I was hurting, I came across this booth on my way out(it was actually beside the booth I was wanting to get some dips from) I was like hummm worth a try. So I rubbed it on my lower back, then continued to rub it in on my hands within Minutes my back was feeling somewhat better, and that's when I knew I had to have some. I bought some on the spot. Took it home, found out my sisters back was bothering her, rubbed it on her and she said this must be in my head but I am feeling better already...and that was right after I put it on. I also have chronic muscle spasms in my upper back and use it on that as well. I am loving this stuff!! Will be ordering more soon!!
