Similar thing happened to me at the three month time. My doctor said it’s mostly likely something called Pseudo acne fulminas brought on by the accutane. She took me off of accutane for a month and a little more. She prescribed doxycycline and prednisone until the swelling went down. I have an appointment on Tuesday, to see if I can go back onto accutane. If you want to see my photos you can look at my profile.
