I had my gallbladder removed about 1 month ago. My pain from surgery has gone away, but I get these extremely sharp pains in the middle of my stomach, under the breast bone, that also radiates through my upper back and shoulders. It causes me to double over, break out in a sweat, turn white. It lasts maybe 10 - 15 minutes and then is gone and I feel fine. I also have GERD and fibromyalgia. Has anyone else experienced this?
