Hi, I'm a brand new member. I've never had fibromyalgia but I had a few miserable years with polymyalgia which I realise is not the same thing at all however I did have a high sed rate and also I was put on prednisone for it and got osteoporosis as a result. While I was going through that period (some years ago) I discovered MSM which is an organic sulPHUR not sulFA
I buy it in crystal form on the internet and put it into every beverage I drink all day, it sits in a sugar bowl on my stove. I have absolutely no arthritis anywhere despite having a damaged knee from a car accident almost 50 years ago (I'm 81). That knee is bone on bone and I was offered a knee replacement which I declined. I believe the MSM is the reason because it is anti inflamatory and you might try it. In the crystalline form it is not expensive, I believe that keeping that in my system all day is why I have no arthritis. You might try it and see if it helps.
