Suggest Treatment For Painful Cysts Under Arms And On Pubic Area

I have been getting cysts under my arms and on my pubic area since I started going through puberty. They are often painful and have had several as large as an egg or larger. They also often have to be lanced. I have never been able to get an accurate diagnosis and have seen several doctors including Dermatologists. I have taken multiple rounds of antibiotics still nothing seems to work. I always have atleast one. After more than 20 years I am tired of being in constant pain.
