<human>: I am a 27 year old woman that has recently in the past week developed a rash on my chest. They look like little pimples with small whiteheads. I pop the whiteheads off and the bumps swell and about 20 to 30 mins later they have whiteheads again. Please help me figure out what this is.
<bot>: Hello. Thanks for writing to us at Chat Doctor I will keep a possibility of Inflammatory acne. Apart from face, acne can also involve the chest, back and shoulder area because these areas are rich in sebaceous glands. If I was the treating doctor I would have certainly started you on Oral antibiotics e.g. either Doxycycline or Azithromycin. Oral antibiotics are indicated if the acne is inflammatory. Topically I usually ask my patients to apply benzoyl peroxide gel, twice daily. It is antibacterial as well as anti-inflammatory. These are prescription medicines, and therefore I suggest you to visit a dermatologist in your region for a confirmatory diagnosis as well as appropriate prescription. Regards
