If you don't know what causes a random headache, that's a good reason to ask a doctor.

if you go to any doctor of any specialization in any point of the world and tell them "doctor, once every three months I get an headache" I guarantee that the answer will be "does it go away with an ibuprofen/paracetamol?"
