im 120 lbs. this problem with my stomach started after i had my son who is now 8yrs old. my stomach will not go down. and when im bloated it gets EVEN BIGGER. i also get stomach pains very often on the left side of my stomach. and im constipated ALOT. An was told i had GERD. i just want a flat stomach. WHAT CAN I DO TO FIX THIS PROBLEM? How much will it cost me out of pocket? will insurance pay?
