I just posted a message, but I also have an entirely different question. Please let me know if anyone has had the same symptoms! A few times a year I will be awakened in the middle of the night with what feels like stomach/intestinal contractions. I will feel a sharp intense pressure from my diaphragm down to my abdomen. It feels like a giant gas pain. I can actually feel th cramps move from one end of my body to another. It feels as if my whole stomach is in a tight knot. The pain subsides for a while then comes back. I also feel chills and nausea, but no vomiting. The attacks last a few hours and end with a small nonproductive BM. In the morning I can go about my business. I have found that they occur after I eat ice cream/ fatty cheeses etc. I have never had a child, but can imagine that the pain is similar to childbirth. Have to say it is the worst pain I have ever experienced. Sound familiar?
