I started with nausea and stomach pain. Now it is fullfledge stomach cramping. It is like a lightswitch. I'll be good for 5-6 hours, no problems. Then it turns on like a lightswitch. That quick! After seven days, it put me in the emergency room. CT scans, nausea medicine, IVs, Etc. Nothing was found. Scheduled colonospy and upper GI, nothing. Did an ultrasound for stones, etc. Nothing. Any solid food makes the lightswitch go on a few hours later. Lasts for maybe 2 hours, sometimes 4 hours and will turn off like a lightswitch. It is so painful! Do I have a valve problem, acid imbalance,what. It has stopped me from doing anything. This is in its 13th day. Where do I go next?
