Dear Doctor, I am 25 yrs old men and working on computer from last 6 yrs, I am having severe pain in my left side of head from last 2 years. This occurs very rarely, but sometimes the pain so much that i cant control myself. I have never consult this to any of the doctor. Can you please suggest me why it is happening and whom should i consult for better treatment or give me some tips if its normal. Thanks and regards, Rafaqat
