I slammed my elbow on my towel rack this morning. it hurts when i move it alittle no bruising can bend it alittle. can i wait it out or should i go in?

Give it a week: You probably have a bruise. If the range of motion does not improve in a week you should get it checked out. Earlier if you're a competitive athlete (baseball pitcher or something)

See doctor: IF there is huge amount of swelling, and you cannot move your elbow probably good idea to see a doctor. If access is an issue, use ice and immobilise your elbow.
