Hi Thanks for writing to Healthcare magic.
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.
