Only three weeks! >:(

A couple of days ago I got a little cut on my right ear. I didn't think much of it and it didn't really hurt or anything. Then today I notice I have started getting little bumps on the right side on the back of my scalp.

They aren't really bothersome but they are kind of oozing a bit, not puss just clear liquid and they kind of crusted over. I counted about eight of them. Not counting the little cut on the back of my ear which isn't even noticable but I can feel it kind of crusted over too. It is like a little patch right and it goes to about mid skull and right to the hairline. They feel like little pimples or something but they are crusted over. Anyone know what this might be?

I'm not going back to class till I get it looked at with a doctor, (I don't feel like ruining someones schedule coming in with some shit and passing it around.). I have been doing research and it seems like it could be a couple of different things.

The really shitty part is I literally just started training three weeks ago. I know I didn't bring it with me because I have never had any thing like this or any kind of infection or rash before. Its going to suck if I am out for another three weeks right off the bat if I got some infection or something. Anyways anyone know what it might be? I am getting it looked at on Thurs. I have never really been one to get sick or anything so I have no clue.

Thanks for the help. And I couldn't get a picture because it is under my hair, I don't know what it looks like.
