My 12 year old son has been having
pain in his upper left quadrant of his
stomach,under the rib cage. We went to hospital and they mentioned it was his bowels backed up in the intestines. Weeks later and he started having these pains again, so i was given him a gas reliever as they told me to give him. He is still having these pains with black stool,headache and sore throat. what type of test should I request and what could be wrong?
