[|Human|] Hi , my 4 year old son had a very bad headache yesterday with low grade fever. Gave him medicine- offered him food- as soon as the food was next to him he threw up- then immediately the fever broke- and headache went away and he was hungry! Infact he ate three bowls of macaroni! Then today he had in the morning- went away. And now he has a headache and low grade as well. Any ideas on what it is? Im planning on taking him to a doctor tomorrow. This had happened a few months ago as well- but not back to back like this week.
[|AI|]  Hi Thanks for writing to Chat Doctor. I have few queries to ask, to have a provisional diagnosis.1. Does he see any aura, I mean does he tell you before headache that he has some flashes of bright light, or odd smell, 2? Is it always associated with fever?3. Is there runny nose or thick discharge from nose?4. Does anyone in family have Migraine?5. Does it subside with pain medicine. With the brief history you have given, to me, it seems to be Migraine. It could well be Sinusitis problem too. Though less likely. Awaiting your answer. In case you answer this queries I will be in better position to diagnose. Else, please rate this answer and close the discussion.
