question: My 16 yr old daughter was on Absorbica ( severe cystic acne) for about 16 wks. Her dosage in last 2-3 weeks was 40 mg twice per day. She is a serious runner (track & cross country teams). When she complained of lower back pain, mood changes, I insisted she discontinue it immediately. It s been almost three months and she still complains of lower back pain. Should she see a rheumatologist? I would appreciate any insight, thank you . Susan
