I have been reading a lot about natural medicine. One book mentioned that MSM has been used successfully to treat this condiiton. (MSM is a biological version of sulfur; it changes cell permeability. It occurs naturally in our bodies.) The book (I believe it called something like "MSM the natural approach to pain") was written by the clinical scientists and MD's who focus on MSM. You can buy MSM in most vitamin aisles of the grocery store or in a health food store.
