Hello. Thanks for writing to us at healthcaremagic 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 caretainly 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 antiinflammatory. 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
