acne
"I had very good results from Minocin as far as my acne was concerned. My face started clearing up and was looking almost back to normal. I did experience the dizziness and frequent yeast infections while on this but thought it was worth it.  After about 3 months, I was feeling very bad, my joints all ached so bad I had decreased my activities and almost stopped dancing. My parents were having me worked up for Arthritis and I was having blood in my stool suddenly. My mom talked to a Doctor at work and found out it was the Minocin that was causing all the joint pain and probably a lesion in my bowels. I immediately stopped it and am now back to normal and have bad acne again."
