I have been in such a terrible flare of fibro and myofascial pain that I'm thinking of going to the ER. I need to break this pain cycle!!! Also, I am having a new and different pain. It started out on the upper left side under my rib cage last week. Now its happening on the right and going through to my back. It comes on sudden and sharp and last for about 1/2 hour. I can't move when it occurs. What do you think I should do?
