Ear problems...?!

Ear problems...?

I was recently on vacation and when I came back, my right ear was swolen, red, hot, and pussing. Not from the inside, though. On the outside. Now it is the same and it hurts really bad. When I first noticed it, it itched for awhile, and now it just hurts.

Any ideas of what it couldn't be? And if so- what can I do to make it go away?

Go see the doc for a little antibiotic cream.. Maybe you just are doing a little reaction to salt, or other natural component, or is it a sunburn?
