<s>[INST] I m a 30 yr. old female. A few months ago I started a new birth control program, low dose microgestin. I take the medicine as instructed. Since I began the treatment I have also begun developing cysts or boils under the skin in my underarms, around my vaginal region, along the insides of my thighs and in the upper part of my nostrils. They swell, contain clear fluid, infected blood and pus. They are extremely painful, especially when they develop in sensitive regions. [/INST] Hi, Birth control pills containing both estrogen and progesterone helps in clearing acne. Progestin only pills can cause acne more often. Hormonal contraceptives can increase sebum production or cause fluctuations in an Chat Doctor.  Since your symptoms are severe, I would suggest you to stop the pills and switch over to another type of contraception. Antibiotic and isotretinoin treatment is required to clear the cystic acne. Take care. Hope I have answered your question. Let me know if I can assist you further.  </s>
