Hi, My Name's Faizan And I Have Been Having Severe

Hi, my name's Faizan and I have been having severe pain sessions from time to time in my head( it's on the upper back side specifically), and these last really long, like six to seven hours a t a stretch, whenever they happen. it occurs two or three times a month, and I have tried headache pills to no effect.
in fact they are not like headaches, there's so much pain even if I look up or tilt my head anyway. Please guide me thank you.
