Why am I having cystic acne with white heads on my shoulders, chest and back?

Hi doctor,

I am having very severe cystic acne mixed with white heads on my shoulders, chest, and back. I have been prescribed Doxycycline, 100 mg twice daily, this is my third week. My acne got worse for the first week and then better. Much less swollen. But it is still very painful, bleeding and oozing through all my clothes. My doctor advised against non-comedogenic lotion, but I find it is making my skin dry, and that is making the acne split open as well as the scabs. Does it take very long to heal? I believe the acne started because I have been using anabolic steroids, but I believe it got infected (as does my doctor) and that is why she prescribed Doxycycline. My question is, what would you do for someone who developed severe cystic acne due to anabolic steroid use? Stopping steroid usage also is not an option at this point as the body and hormones could not recover on their own. Please tell me how this would affect your treatment and how health insurance would be affected.
