greetings friend, there are many causes of back and abdominal pain
that he might be concerned about, including pancreas problems, ulcers, gallbladder
problems, acid reflux
, and aortic aneurysms. Fortunately, most of these are unlikely unless the symptoms are severe and persistent. If they are, he should seek a doctor because these are significant symptoms with treatable causes. Also back pain
can radiate into the stomach and cause symptoms as well even if there is no attributable cause to the pain. If her pain persists for a couple of days or significantly worsens, I would seek medical attention. cheers.
