ever think its not muscular skeletal at all,and more like digestive?
could be gallbladder or pancreas.
I just expierenced the same exact episode 2 nights ago. Mine started in the mid-back, radiated around my rib cage, then went to my sternum. My pain was so intense that I had to go to the emergency room (which I have only ever had to do 1 other time in my life for anything pain related problems). They had to give me two doses of Morphine and some other pain medication just so I would be able to lay down long enough to do the MRI. Did you expierence any nausea with your symptoms? I would vomit about every hour. When I was discharged from the hospital, they diagnosed me with "Median Arcruate Ligament Syndrome," although I'm not totally convinced that that is what it is after doing some reading about it on the internet. Everything I have read said that the biggest symptoms are abdominal pain and not eating. I had no abdominal pain (only nausea) and, although that it started at 10:00pm for me, I didn't feel like I wasn't hungry. The pain was so intense that I didn't really even think about eating. I saw that you had posted your message in September of 2008 and I was just wondering if you had found anything out since then. Was it pregnancy related? Have you had anymore episodes? I am very interested in hearing what you have found out.
