Skin sore keeps getting re-infected!?

I have a small sore on my lower abdomen, just above the pubic area. It originally looked like a pimple. Over the last few months, I have disinfected it with alcohol, peroxide, and Neosporin. (Not all at the same time!) I have kept it bandaged. I have let it "breathe." I have drained it. I went to the doctor and got an antibiotic. Nothing is helping! It keeps almost healing, then suddenly gets infected again!

Seriously, what else can I do??? BTW, I know it's not an STD. Someone please help!

Peroxide won't do anything but alcohol and Neosporin (yes, at the same time) should have done the trick.

When you "drained" it...what did you do? THAT is the big problem here. YOU don't drain anything. That's for a doctor to do.

Go back to the doctor and please leave it alone. Do not touch it. It is likely an ingrown hair or some other dermatological thing.
