Try bio-freeze, read below.. You can't buy it at a retail store, but you can get it at your local chiropractors office, its about $16 for a roll-on bottle, I would just call around to the closes office to you and ask if they sell it, that's what I did and the first one I called said yes... I use it for my neck.
