I am 32f, saw derm for terrible breakouts on back that I've never had before. Diagnosed foliculitis and acne. Prescribed doxy and clindamiacin cream. Doxy caused vommiting so he switched to keflex. After one week no improvement, back is worse, face is same. Caused yeast infection plus bad feminine itch. Holding out in hopes it will work soon, but it's not looking good. I don't understand how I could have a clear back all my life and now all of a sudden there are zits Everywhere all over it.
