HI Brenda ! I am Dr Shareef, a general surgeon answering your query. From your history, if I would have been your treating doctor, I would have investigated you in lines of pancreatitis, specially if you consume any alcoholic drinks. The pain of pancreatitis is very severe, sometimes radiating to back. This can be diagnosed by an increased amylase/lipase level of the collected blood, and preferably a CT scan after doing a preliminary ultrasound abdomen. Pain of chostochondritis may be there in the rib margins, but possibly will not radiate to the back. For the present, you take a proton pump inhibitor, and a probiotic agent during the investigation time. Thanks and good luck. Thank you and good luck.
