Hi Kiran, I am a nurse, and have a son who is battling chronic headaches with belly pain as well.  As we are going thru evaluation for this with a doctor we have seen that one of his liver lab amounts is high, therefore we will do further bloodwork to see why. My point to you is that you SHOULD be seeing a doctor...either a very experienced "internal medicine" doc or better yet, a neurologist.  Call your insurance and see what you have to do to get them to pay for you to have a neurology consult.  I would not waste your youth hoping they will go away, but treat them and LIVE!  They are NOT normal, but they may be treatable.  Also, make sure you are eating well, have a healthy weight (Weight watchers is great if you need help there), and exercise.  These things will help you too. I HOPE you find a good treatment and can consider this a minor inconvenience in your life in the future.  God bless you!  K
