Did I pull a muscle after falling on my bike yesterday?

Yesterday my shoelace caught on my bike pedal. I got pinned between the handle bars and the ground. I had to twist the to get up, but I managed to bend the bar. A few hours later I got a very severe shock of pain in my upper arm muscle. It's been over 24 hours and it hurts worse than yesterday. I can barely move it without the pain. Is it just pulled and how should I treat it the fastest?
