I have been headache from last 1-2 year , so i got a specs of power , but despite using specs i m not in relieve from my headace. Mostly it start from the exposure in sun of 10-15 min or after some fatigue or by constant fast air (like in buus with open window or during bike riding) or reading from laptop or book or even in lecture(in 1-2 our of concentration) and it last untill i take a sleep of minimum 2-3 hours. I am in too much pain. it affects my all activities like study and all
