I had a small cut, likely from shaving, between my vagina and hip bone--in that region. I noticed a lump, that was hard, and didn't really move, about 2 or 3 days ago. I tried to poke it, with a needle, thinking if it were an infection, I should relieve the pressure/pus, and clean thoroughly. I could not penetrate the lump, but some liquid appeared to be releasing. I cleaned with alcohol, and put a band-aid with antibiotic ointment on it. 2-3 days later, the lump is still there. I pushed the lump, and puss did come out. However, no change the lump's size or placement. Is this something I should wait out? The lump is oblong,but about the length of a paperclip, though a bit thicker.
