My 3 year old was complaining about belly button pain yesterday, he seemed cheerful enough so I thought nothing of it. Now he is pointing to the right lower abdomen saying It hurts. He doesn't seem in severe pain, but now he has a fever and is very pale. He has a cough too...so I'm not sure if the temp is related to the belly pain or if there are two different things going on. Anyone have any advice or thoughts?
