Broken or jammed?

Last night on our walk, I accidently bumped my middle toe on the back tire of Crew's wheelchair. It hurt quite a bit but the pain went away after about 15 minutes. Then, in the middle of the night I noticed it hurt when I curled my toes. Today, it is slightly swollen. I was still able to run today but it hurts most when going up hill. Do you think it is jammed? I wondered if it was broken at first.... but if it was, would I even be able to run at all?
