Hmm, but there are some blood tests showing typical changes in people with Fibro/CFS tart hat do not fit to an infection. These are not regular tests but only bloodwork comparisons done in studies, but I wonder if BFSers would show the same changes if they would do a study on people diagnosed with BFS. I agree that it might be brought on to some people by a virus, but not all for sure. If it was, why do 80% of all people with hypermobility syndrome (like me) get fibro, and why have many people that develop it a history of health anxiety? Why are more women getting Fibromyalgia that men? And why does it usually start in the 30's ?
