When I was younger, my knees would crack if I just bent them. Having finished puberty, I have not had this problem. However, after about 2 weeks on accutane, my knees crack very easily (everytime I bend them). In general, all my joints crack very easily now. Is this a cause of concern? Should I be worried about arthirits/poor joint health due to accutane? I have read some people developing chronic joint pain due to accutane. Is there anything I can do to prevent joint damage/stop the cracking?
