Hello everybody,

I have a bit of a problem. I have this moderate headache that is virtually unexplainable. I have went to many professionals (neurologist, cardiologist...), tried many OTC headache drugs, but still the ache persists. None of the doctors could expplain the reason for the headache. Since I'm still a student, when I try to study a material the headache increases and basically I can't learn anything. It feels like a brain blockage.

To my mind it's from overexhaustion, but what do you think?
