question: HI, i AM A 54 YEAR OLD FEMALE AND TWICE THIS WEEK (ABOUT 6 DAYS APART) i HAVE HAD SUDDEN SEVERE PAIN IN MY ABDOMEN FOLLOWED BY SWEATING AND BURNING SENSATION UP MY ARMS AND SEVERE DIZZINESS FOLLOWED BY A BOWEL MOVEMENT AND THEN DIARRHEA . AFTER THIS PASSESS THE SYMPTOMS USUALLY SUBSIDE. WHAT ARE THE POSSIBLE CAUSES OF THIS? COULD IT BE IBS OR ANXIETY RELATED?
