Have you tried Topricin?
A friend of mine is having severe knee pain, and a friend of hers strongly recommended Topricin, a homeopathic (no side effects) cream. I looked at the website and read some of the reviews there and on Amazon, iHerb, and Vitacost. I'm planning to order a jar.
Anyone tried it? I never even heard of it.
