I have a pulsating pain that started yesterday afternoon, in my upper abdomen right btw the rib cage. I am 27 yrs old 5'3 112 IBS, have had pancreatitis 6 times since i was 18. Do not use alcohol. I have a lower functioning gallbladder and my stomach empties out slower than normal. I have a history of bulimia and anorexia, but now mostly bulimia. This pain kept me up all night, I was vomitting but it was white foam. It feels like someone is grabing something and squeazing it. it intensifies, and then subsides. I haven't been sick for approx 5 years. Do you think I should be concerned? I really don't like going to the doctor.
