The front chest muscle often goes in to spasms. The pain is getting worse and unbearable. The pain has traveled from back of muscle just above elbow down to top of forearmrm midway. There is something that feels like a wire(tendon ?) from elbow to wrist that is tight on the underside of the forearm. There is also a muscle in the back that is really notted up and runs from the spine about mid back up and under the shoulder blade.
