my son has green diarrhea and stomach pains and is sick at his stomach, he has had a liver transplant 14 years ago, no gall bladder, on alot of med, he just took milk of magnesia because his stomach was bloated, I did call med link and spoke to the dr and he didnt sound alarmed...but he went from being clogged to now diarrhea , should I be worried...he is still having stomach pains
