I'm curious about what you describe. I have had BFS without much in the way of muscle pain for 16 months. My story is that two weeks ago I developed a very severe pain in the right upper quadrant of my abdomen and lower anterior R chest wall. 8/10 in terms of severity. Was convinced it was gallbladder and, being a doc myself, arranged the relevant tests - all normal. So I went off to an osteopath on the basis that it was muscular/ referred from my spine. She did all the right things and made my back make loud clicking noises and also worked on my rib cage, where she said the problem was. This has helped to some extent but now I have the most diffuse and unpleasant muscle pain in my shoulders/ scapulae etc... all very much like my fibromyalgia patients. I had thought that the osteopath had corrected my previously lousy posture and that the pain I was experiencing was secondary to this but, having read your post, I wonder whether there is a bit of a fibromyalgia thing going on for me too. I'm back to see the osteopath on Monay so it'll be intersting to see what she says.All the bestSimon
