My ds6 came down with a sick/poo bug during Christmas Eve and was poorly for xmas day, he hasnt been sick since then but hasnt bounced back either. He isnt eating properly and doesnt fancy much....even when offered any treat he desires.....He hasnt had a temperature but is really not himself. He is lying around most of the time and is very pale and has dark circles under his eyes. He is in bed now and is quietly lying down.....which he never does! I spoke to Dr today and he said it was probably Post Viral Nausea! Havent heard of this before. He said it can grumble on for a week or so after a bug. Before the bug occured Ds did complain of "his tummy burning" We just thought he needed a poo. He is still describing it in the same way. This morning when he woke up he was really tearful about how his tummy felt. Am I overlooking anything. Dr told me that if it was appendix he would be a lot sicker. Any advice?
