DS has been poorly for about a week now. He started off with a high temperature about a week ago. He complained of a sore tongue, and appeared to have some sort of ulcer, (which has gone now).He then started to complain of stomach pain, it comes on mostly in the afternoon/ evening and appears quite bad. He is often rolling around on his bed crying and holding his stomach. We have taken him to A&E twice, they have Xrayed him, but couldnt find anything to suggest the cause of the pain. Will be going to GP tomorrow to ask for refferal to a peadetrician. Any one have any idea what could be causing this?It is very distressing to see him this way.
