Possible elbow injury? (read details)
Someone (totally not me) slammed into a steel door that was caught on warped concrete... elbow (funnybone kinda area) hit the handle and hurt a bit... It was about an hour before I could look at it and take care of it. R.I.C.E. was applied within 10 minutes just in case. It's been in a sling for about half an hour now, with R.I.C.E. still. For the past roughly 45 minutes or so it's been alternating between fever hot and pond cold, cycles of maybe ten minutes with a bit of normality in between. There's a little bit of swelling in the area and a tiny bruise, but no other visible damage. It doesn't hurt unless I change the angle of the elbow or put any strain on it (the pressure of buttering a bagel hurt some).
Is something seriously wrong with it, and what else can I do about it?
