question: I have slight swelling in the crease of my arm where my elbow bends oin my left arm. It is not painful there, but my arm as been hurting slightly in my forearm and in my shoulder. I don t think it s heart related because I recently went to a cardiologist who did a stress test, heart calcium score test, and several EKG s and said everything was good. Just worried it may be a clot or something. It s a little red too and hard.
