Recurrent Vaginal boils. It is painful.

Near my vaginal lips, I have got swollen area which turns later to Red, Pain, filled with pus. The first time i had this was 7 years back but it was not recurrent that time. Since last 2 years it grows every 4 to 5 months gap. I had an incision around my upper thigh due to this 5 years back. I have already consulted an Gynee alot of time, they put me on antibiotics. The only reason they provide me of this problem is: Stay clean and use cotton panties. Avoid using razor or cream on pubic area. I am following all these instructions still i am not getting rid of these vaiginal boils. Right now I have 2 vaginal boils, one of them is healed as I took a medicine (Ciplox-500) by self and it burset within 4 days. Right after that another one grows, I consulted a gynee, she has putting me on antibiotics ( Augmentin duo, pan 40, Zinese, Lizylac). It has been 4 days Im taking these medicines. I do not feel better, boil it still there, neither it grows nor it has reduced in size and it is painful.
