My Son Has Been Playing Football For Two Weeks And Is Losing Weight In His Stomach. He's Been Complaining About Pain And Has Loose Stools. Do You Think It Could Be His Stomach Tightening Or Something More Complicated?
My son has been playing football for a few weeks and lately he's been complaining about his stomach hurting and loose stools. He's lost weight and I'm wondering if it could be due to his stomach muscles getting tighter.
