my 10yr old son has been sick since Wed 11/9; he was vomitting and had severe stomach pains mainly by his belly button; when you push on his stomach he really complains of pain/or pushing from the lower back on the left side. Also his white blood cell count was at 13.1 Wed and then on Thurs it dropped to 3 (in a 24 hour time frame) Today is his 3rd day of stomach pains, he has stopped vomitting and has kept soups/toast/jello down for 24 hours now. I am concerned about the white blood cell count dropping as I could not get a straight answer as to whats too low? Also he has a yellowish look about him for the 3 days as well the whites of his eyes are grey with red lines, the corners have a little yellowish look to them not alot. Is this something I should be more concerned about? They did a CT and the general surgeon stated not an appendicitis.
