After years of many doctors, medicines and tests, I'm in my 1st major flare-up of "Fibromyalgia", including all the above listed symptoms. As patients, we seem to notice our aches and pains, but disregard them when relaying symptoms to doctors. We forget or don't mention minor or "unaffiliated" problems. I have several Medical Specialists that were treating me for the individual "complaints" of Fibromyaligia, but the complaints were never grouped before, for a diagnosis! Sometimes we have to be pro-active, to facilitate the process. (I often use Web M.D. Symptom Checker, as a kick-off point.) "Lower left stomach hard" could be constipation.
