Had gall bladder removed 3 years ago. I have severe pain right side of abdomin after eating followed by dirrhea,sweating,vomitting and severe pain with stabbing in back. Feels like someone is squeezing my insides. I have had many test cts,emptying digestives test,colonoscopy,blood work,ultrasounds and many endiscopies. Pain starts about 30 mintues after eating and sometimes last for 7-8 hours followed by extreme belly swelling.
