Hi, My upper right arm has felt like its in a constant vice grip for the last 3 weeks. The pain starts in my upper bicep close to my sholder and shoots a constant pain all the way to my fingers. I have never had this issue other than a torn muscle in my sholder blade that is simular to a rubberband.. i forget what its called.. lol. But back to my issue the pain sometimes hurts so bad I try to prevent from useing it. Heat and massage sometimes helps but soon returns within a matter of min after stoping. Im a cna and fear that i will no longer have the capabilities of performing my duties. Please help.
