I learned about this just the other day, my local druggist used it for his wife's surgery wound when nothing else worked, his doctor told him to do it, so now he's going to carry it in his drug store.

I'm going to buy some just in case I have an issue the longer it takes to heal the bigger the scar tissue is under the skin, and that's what makes for a stiff knee besides not walking enough like my wife, which I gave up pushing on. I assume you've reached the point were you were told to use a cane, and didn't like that.
