I am feeling headache , means when calm and thinking something,or going to sleep.the pain is burning type. when busy in some other work or divert my mind then somehow ok. but then immediate started. i have also lost so many hair due to this, what do i think.mainly when thinking something and when i will think that the pain will come then also.it is now last 02 months. i felt like this in 2005 but for a short period.kindly suggest me.i am also thought this is due to gas problem because i am also suffering from gas problem like chest burn etc, but dont think so.
