WTF have I done to myself???

A few days ago I recall, rther vaguely, banging my elbow.  I've got a memory of thinking, "ow, that's going to hurt".  Then nothing happened and I ignored it.

Bloody Hell, my elbow is agony.  It's tender, swollen and feels slightly warm to the touch and is throbbing gently.  It started getting bad last night and reached its current peak around bed time.  It's still the same this morning.

Another day of this and I think I'll need to find some medical attention.

Can I just say again, OWWWW!
