I experience severe boils in my underarms and pelvic area. It is puss filled. It generally comes before periods. They grow very big and get puss filled inside the skin, then in 2-3 days it opens up to the surface and bursts out. The fluid is yellowish white. I mostly get it in the same place. The sizes are generally 2-3cm. I have PCOD. I have shown dermatologist physically, she gave me antifungal ointment and medicine. But as the medicine course got over. I got it back. I need to know what can be a permanent cure. And what medicine can help the most. Also yes i am trying to lose weight.
