Tummy issues!

I am not sure what is going on with Jaxson!He has had some stomach issues and i cant seem to get any answers from the doctors.He has been horribly gassy,vomiting,and his tummy is tender to the touch.At first i thought he was back ed up and he is super sensitive to that.But that is not what is going on.He is miserable.So i will call his doctor tomorrow in hopes of him being seen.I cant stand my little one hurting like this.
