Ritilan is a stimulant and affects dopamine in the brain, just like cocaine. I don't know about ritilan too much, but I did snort a lot of coke and did some damage to my nose. Although it may not be exactly the same, I am assuming it's close to the same type of damage on the nose as coke.
If your dr looked in your nose and said it's fine than there is your proof. He didn't see a hole or anything like that, and if it's just a few scratches consider yourself lucky, cause that will heal. Mine took a few months for the pain and scabs and blood to stop, blah. If a hole is made, then NO, that won't heal, but all the lining and tissue usually will. There are worse problems then worrying about your nose here. Congrats on 9 days clean, keep it that way. This is a great support group so stick around. Good luck.
