For the last 10 or 11 years I've been having these awful spells that make my life miserable. The doctors have been unable to diagnose the problem. The spells start with a sudden dull ache in my back, which gets worse quickly, spreads to my stomach, and my entire abdomen blows up as high into my chest as it can go, making it hard to breathe. The bloating and pain increase at a fast pace. I have pain in my entire back, shoulders, neck, and arms. Eventually I start vomiting, not from nausea but from pain. Once I get really emptied out, the pain is gone almost as quickly as it started. There is no pattern to these spells. It doesn't seem to matter if I've eaten at all or what I've eaten. I had a hip revision 8 weeks ago, and since the surgery, the spells have increased in frequency. Before the surgery, it had been months since I had a spell. I've wondered if it might be related to muscle spasms, but have no way of knowing. Gall bladder problems have been ruled out, as has heart trouble. I haven't even been to church since the surgery for fear of having one of those wild spells in public. Can anyone help? Thank you so much!
