In the last two days my left arm, just above the elbow and down through most of the forearm has at times suddenly grown painful, almost as if I hit my funnybone, but without the tingling. It shows up mostly on the outside of the elbow. I am a heart patient, and had a stent put in this last june but the doctor has said that everything is fine. Lastly, I have had two heart attacks, but barely noticed either one of them (slight tightness in the chest)
