my 9 year old son has had the stomach virus 3 times in the last 30 days. i took him to his Dr. Friday because he has diarreah every morning first thing, he is pale, dark under his eyes, cold with no apparent fever and complains of severe abdominal pain and leg cramps. they took blood, urine and I have to collect stool tomorrow then he can start on bactrim. Now he is having horrible headaches. What is going on? They are checking him for shigillosis, but he only has about 2 of the symptoms of that. i have Chrones but his is not like what i do. Any suggestons for what i can do to hep him?
