I had a skin boil/abscess just near the lips of my vagina a week ago. I got antibiotics and the boil drained fully and was well on its way to healing completely however its come back (2 days after finishing my antibiotic 7 day course). So rushed to the doctors and got the same antibiotics for another 7 days. What will happen now? The boil is extremely red and big but has no puss formation as yet. Will the antibiotics stop the puss from forming or promote it? Will I need to surgically drain it?
