I went to Rite Aid, and got a dedication contains camphor 4% menthol 10% and methyl salicylate 30% I wonder if it is for mussel or bone or both? And is there problem from using it for long term?
I use a medicine call Voltaren gel. It has diclofenac sodium. I rub it on my knees and it relieves the pain. Or you can take pills, but those have more side effects.
