im suffering from headaches for the past years and it got worse recently.

whenever my headache comes, i would feel nausea and a very bad pain at the back of my head. its like as if something is stabbing my brain. most of the times, i guess my headaches are caused by sleeping too much and lazing at home. are those really the cause of my headache? and everytime i would consume panadol to ease the pain.

may anyone tell me what actually im suffering from and how could i do to stop the pain besides having panadol?

please help!
