Our 6 year old has been complaining about stomach pain for weeks now - we had him in A&E twice as he was in tears with the pain. It’s not as bad now but he’s still saying it hurts every day and occasionally crying. He’s had full blood tests, urine, pooh etc and all clear - no vomiting and stomach function seems normal. At a loss as to what to do now. Any ideas on what it could be??
