Fibromyalgia makes every muscle in your body hurt during a bad flare, makes sitting and sleeping hurt, anyone touches you it hurts... imagine a giant bruise covering your entire body to give you pain but no actual bruising. Smaller flares do seem to hit me the most in my feet and ankle joints, sometimes knees and hips. To test they press all over your body and if you flinch in 7 or more spots you have it. Pressure points are in spots you would not normally hurt, like the outside of my hips, insides of my knees, several back spots... one spot is almost exactly where Spock does the Vulcan nerve pinch on Star Trek lol.
