Is Cholecystectomy Advisable For Severe Pain In Abdomen?

MY GASTROENTEROLOGIST HAS DIAGNOSED ME AS NEEDING MY GALL BLADDER REMOVED. HE SAYS IF I AM IN PAIN I SHOULD GO TO THE ER. ULTRASOUND AND BLOOD TEST CONFIRMED HIS DIAGNOSIS. BUT HE MADE AN APPT WITH SURGEON FOR TWO DAYS FROM NOW WITH THE CAVEAT THAT I GO TO ER IF I CAN T TAKE THE PAIN. HOW MUCH PAIN IS TOO MUCH PAIN? WHAT IS THE DOWN-SIDE OF WAITING?
