HELP!

a guy came over in the evening today. the 3 of us guys discussed about our project for an hour or two. it was at least rather productive...

but that's not my main topic.

*serious tone*

i know people will just tell me to see the doctor, but here goes... don't read if you gross out easily.

i've got a skin problem on my back. and a bit of my upper arm(a bit = 1% of the skin at that area) as well. it looks like pimples. could be acne. but i'm not sure. they are little red bumps of different sizes. they don't itch. sometimes if i happen to squeeze them (out of boredom) i'd probably broken the bump and some stuff come out. i'm not sure what. there may be transparent liquid(plasma?) or pus(or whatever you call that after you squeeze a pimple) upon squeezing. i repeat - it does not itch. it seems to be limited to my back area.

so i'm just wondering what i can do to improve the situation. ideas, anyone?
