I am 34, male, 64 kgs. Suffering from headache for last 12 yrs. Feel pain mainly backside and middle of my head. There are no exact time for it. Sometime it started when I exhausted after daylong of study or work, sometime after roaming in the sunshine, sometime spent longtime in empty stomach. Just 1/2 hours before I feel weightless and irritating in my neck, head and eyes then it started slowly and then deeply. It likes someone hammering on my head. I tied up my head with a piece of clothes and feel quite better, close my eyes and laid down to feel better. Last about 2 yrs. I feel the pain less than before. I used pain killer tab. Diclowin plus when l failed to tolerate the pain more. I take treatments from doctors but in vain.
