I’ve gone to the ER 5 times now for severe stomach pain that happens randomly. Sometimes it’ll start off with abdominal pain during a bowel movement. I know an attack is coming because during my bowel movement I will start to sweat, get the chills and look flushed. Right after that I will start to feel nauseasc vomit and dry heave for 24 hours with the most excruciating pain in my upper abdominal area . It makes me feel weak, hard to talk or even keep my eyes open. Usually after 24 hours have gone by, I’ll feel a final urge to puke and it’ll be a projectile vomit and then all of a sudden I feel relieved after my last vomit. All my test at the er (blood, urine, ct scan, ultrasound) came back normal. I’ve had an endoscopy and colonoscopy and only showed some mild inflammation. I’ve been tested for celiac and that came back negative. This has happened 4 times in the past 5 months. And twice last year. Waiting to take more tests to see what is is, has any one else experienced this??
