Messed up my elbow?

[breakingnews]

Any time you have loss of motion is generally a sign to at least have an X-Ray taken. Particularly if there is a lot of pain - may be some busted or damaged tendons. And then once you know, you can judge future injuries against that one, though internal damage is tough to tell from exterior prodding (unless you're a doctor).

Of course if it just hurts to move something, it's probably just swelling and nothing extremely serious. That's diff from range of motion. I have some damage in my left ankle from not getting it checked out after spraining it ... of course now it's fully damage from breaking it 3 years ago, but still.
