I posted under costochondritis to another lady as I get this too, BUT I have no idea what is going on with my body this past week. Very weird. I get these muscle aches quite often and now I am in a horrible flare. It's my entire rib cage, shoulder blades and collar bones. It seems like it is in both sides (like all around my middle). This flare has been wierd--one day my lower back and hips hurt, the next day it's my shoulders and neck, then a headache, then my ribs, AND it seems to move around each day. Muscles aches, tissues burn... I can't figure out if this what you all call a FIBRO flare? I don't understand it -- it scares me AND the doctors have no clue. Anyone else like this????? Please respond --I need to know if I'm the only one!
