A couple of days ago, I was having some pain when I bent over to reach for something in a seated position. I've had this pain for a long time. I just thought it was an ulcer. How am I suppose to know what is, and isn't the fibromyalgia? Last night was the worst of the pain. It's located right below my right breast, and just above a rib. I can now feel it with my hand. Not just from the inside anymore. I couldn't eat again yesterday because of it. It makes me feel nauseated. I really hate this disease! You can not tell what is the fibromyalgia, or something else.
