osteoarthritis
"I tried this for my pain from a  3 disc spinal fusion and I might as well have spread melted chocolate for all the good these things do. I tried the box of 20 patches, ingredients camphor, wintergreen and methyl salicylate. Don't waste your money. All you do is walk around reeking of camphor and wintergreen, and it has almost NO effect as far as pain. The ads for this are very deceiving. I'd rate this product with a minus if I had the option."
