It could very well be that you just have a small infection, if peroxide clears it up, you have nothing to worry about, if after about 4 days of cleaning with peroxide (then rinsing with water) it dosen't go away, you should see a doctor.

You can try peroxide as a cleanser for it. If that dosen't work after about 4 days, you will want to see a doctor. You might get some other answers on here, so just hang tight.
