There are no definitive laboratory tests for fibromyalgia as of now. Your doctor should take blood tests – but only to eliminate other possible causes for the symptoms that you are experiencing. Having eliminated other possibilities, the doctor then looks to see if you have experienced widespread pain in all four quadrants of the body for at least three months, and displays many of the other common symptoms of FMS, including at least 11 painful tender points. Fibromyalgia is related to arthritis which means it includes inflammation of the muscle. Soft tissue inflammation responds well to minerals which improve blood flow. MSM, organic sulfur, is one of the products which helps improve blood flow. We do not get enough organic sulfur in our diet because when we heat foods, the MSM is cooked off as steam.
