Headache throughout the day. Right side.

I've had one sided headache that starts from the neck and goes all the way to the eye. There is an electric shock like an itching kind of sensation on the top right side of the head. It's been two years since I've had this kind of pain on a daily basis. A doctor at NIMHANS had prescribed tab sibellium 10mg for 3 months. Didn't complete the course as my headache disappeared only with 2 tablets.. I took it for 1 month... It's been 4 months since I stopped taking sibellium and the headache again came back with excessive daytime sleepiness and nighttime sleep disturbances accompanied with poking pain on the top left side of the head with pain on the left eye nerve only when I move it towards the far right side.
