Hi,
Even me too got headache oftenly in my childhood days when i was in 6th std.At age 31 it was discovered a colloid cyst was formed in brain.Now it is removed.
No headache,
I suggest you to visit neuro surgreon for CT scan

I would think that you need to bring this up with a doctor.
It could be migraines, sinus (I get sinus headaches every night in bed), or so much that you need to be seen but it could be so much that is not a tumor.
