I believed that's what I had for the longest time until I finally ran into my buddy who is a Phisio-therapist. He pushed around here and there until finally (without telling me of course, due to the flinch factor) he snapped my elbow back into place. He said that sometimes with the elbow it can sit just a hair out of place and one quick snap, it was right as rain. I told him how great it felt as soon as he was done and he told me "just wait till tomorrow, then it'll hurt" and he was right. Haven't had a problem since.
Moral of the story, if you haven't already, see a Physio!!! They're the pros!!
