It could be a number of things with just that information. What side of your stomache area does it hurt the most? What does the pain you are experiencing feel like? If anything if you are that worried about either make an appoinment with your Doctor or go to the hospital. If finacially you are unable to either of those things look for a free clinic or a low income clinic they are out there just look for them.
