My 15 year old son has had a bad headache and nausea at times for 18 days now. Pain wise his headache goes between a 6-9. GP checked him. Diagnosed migraine Hospital checked him, agree with migraine, CT scan clear. We are starting to wonder if he's telling the truth. We've sent him to school a few times but he comes home after a couple of hours saying the pain is a 10 and feels sick. I'm thinking he doesn't want to be at school but he says he's not lying but does prefer to be home. I hate to doubt him. But surely a migraine would have stopped by now. He's taking ibuprofen/paracetamol and anti sickness pills.
