Hello everyone! Well this is my first post, so i hope I do it right. I've been on Accutane for about two weeks now. I'm a little bit (ok really) nervous about it though. So far, I've experienced pretty much no changes in my skin (except dryness of course), but I am having a problem with chest tightness, upper back pain, and rib pain. Is this normal? Has anyone else experienced this? Any info would be helpful.
