Unidentified abdominal pain
I wasnt sure where to ask this, but I've had severe abdominal pain for 16 years. Pain radiating from my back all the way around and sharp upper right abdomen pain. Lasted a few hours-a day for 16 years a couple times a year. Then recently i had an episode that went off and on for two weeks straight. Now when it happens theres pressure all around my abdomen and back, and sharp pains randomly around my torso, no sharp pain felt when they push on my abdomen, all blood and urine tests good, xray and ultrasound show nothing. Doesnt seem to be linked to eating seems to happen at random. Anyone experienced anything like this?
