I have a friend, and his pastel male had some skin issues that rose from poor husbandry. It was in a to moist of an environment with poor cleaning practices. The snake had a stuck shed for a while which I got off with husbandry improvement. There are still some problems with the skin, but overall he is bouncing back I believe. He does have white spots all along his body that I believe are scar tissues, but I haven't been able to find any pictures on here to confirm my thoughts, at least not through my phone.
Here is a pic of the snake in question-
