My seven-year-old son has pain centered at his belly button, which worsens with touch and is all over his abdomen . He has a fever ov 101.8, a sore throat and some, not much coughing. I gave him some pain & fever reducer, and he s trying to sleep. It s 3 am, and he complained of stomach pain yesterday at breakfast (attributed to hunger) and again this pain at bedtime, waking up at 2am. Should I be concerned with appendicitis or another emergency?
