I am 22 years old, and about a week ago I slipped and fell on my left elbow. It was my first fall in a long time ago. My arm was hurting, but I thought that I had fallen when I was younger and everything was fine, so it would be fine this time too. But the following night my arm became very swollen and it hurt to bend or stretch my arm. In a few days the pain got better, but I still had trouble stretching my arm or picking things up, so I went to see a doctor.
