I fell going up some slippery steps almost a year ago. I was holding items and hit my left elbow on a handrail. There was severe pain for a few minutes, and later some tingling/numbness. It hurt that day, and then some lesser pain for a couple days. For a few months it would hurt if I laid on it funny when I was in bed, or on arm rests in chairs, vehicle. I didn\’t notice it for a couple months, but I still get pain occasionally when laying on it, arm rests. Elbow/arm seems to function fine, but should I worry?
