Has anyone experienced this?

Hello,
I have been on accutane for about a week. 40mg/day. The last couple days I noticed when I laid down to rest I would get a pain in my back (not my spine) that lasted for about 30 seconds and then went away. Almost like my back needs to get used to laying down. I think it may be muscle aches in the muscles in my back, but I dont have muscle aches anywhere else. anyone have the same experience?

Dark circles under eyes..Permanent?

Hello,
I am currently on accutane and everything seems to be going well. One problem I have is that I have noticed that the skin under my eyes has gotten darker (nothing major, but something i definately dont want, since i am a 17 year old male) I read from various places that this is caused by the thin skin and something with the blood vessels. I also started taking a vitamin K supplement to combat this...I drink lots of water, get a LOT of sleep, eat well, etc...I was just wondering if there were people out there who also experienced this, and if it went away after you course...if the dark circles are just from thin skin and it will go back to normal after i stop accutane then i am fine with that
