It's amazing that you should ask this question, because yesterday I had a really bad pain in my hip so went to the drug store to see what they could offer over the counter. The pharmacist suggested 'Neuragen' made by a company called Origin Biomed. I was sceptical because it's a liquid, and I wanted pills. Anyway, I bought it, took it home, and applied a couple of drops on my hip: 15 minutes later the pain was gone!! It's not cheap at $30 (around 15 pounds) for a small bottle, but well worth it...I think.
