M.S.
I think you should read the OmegaRx Zone by Barry Sears (you can check it out from the library). He talks about how really high doses of ultra-pure pharmaceutical grade fish oil can work miracles with pain, inflammation, arthritis, auto-immune disorders, and more. I learned a lot.
Also, just yesterday I was checking out an MD that specializes in alternative treatments and has a clinic in my area (I don't know where you are, but he's in Carson City, NV). I think it's called the Nevada Center of Alternative and Anti-Aging Medicine. His name is Dr. Frank Shallenberger, and he's written a book, so they have a lot of out of town appointments. Anyway, check out his website www.antiagingmedicine.com. He does "Prolozone therapy" for joints that supposedly corrects the pathology in 75% of cases. It might be worth looking into at least. I know there's just so much information - it's hard to know what to do. Good luck with everything. I hope your sweet daughter gets well soon.
