May be you should use Glasses while you work on your PC. I am also suffering from it. - Mr.President -
take a tablet will help and glasses will help too . I advise not to work on pc . while u have headache . just sleep for a while .
@My220x just drink a glass of water mixed with a tsp of honey on empty stomach. i read it somewhere. hope this should help. all the best.
put light pressure on your temples to relieve the pain. Gently rock your leg from side to side to take your mind away from the pain, it really helps. Take pain killers if you want, and get a bit of fresh air.
