I have a really bad pain somebody help?

It sounds to me like really bad heartburn. Whenever i get it I get it really bad and my jaw starts to hurt and both of my arms and my shoulders and it's soo bad that I just lay on the floor with my arms stretched above me and cry. Since you shouldn't lay on your back, try laying on the side. Also, try drinking a gl of milk, it's known to help heartburn, but just in case you should call your doc anyway and let him know!! :) Good luck1
