HOSPITAL STAY FOR 4 DAYS. HE IS HOME NOW BUT EXPERIENCING A LOT OF BACK PAIN. BLOOD PRESSURE IS OKAY. WHAT IS CAUSING THE BACK PAIN YYYY@YYYY HOW LONG WILL IT TAKE FOR THE BODY TO ABSORB THE BLOOD IN HIS ABDOMEN? Doctor: Dear friend, I understood  your concerns, see this is called as peptic ulcer or you May have ulcerative collitis, then only you may have bleeding in stomach or intestine,  as your ulcers heals your bleeding stops and pain also decrease... and pain in back may be due to weakness or spasm in muscles so we need to take ice treatment for pain reduction. Within 15days pain will decrease. You have to improve your posture also..
