Bad shedding on my ball python?

My ball python is currently shedding and I fed him today, since he can't see I picked him up with the end of a broom stick to get him out of his cage to feed him so he wouldn't mistake my hand for a meal. When I put him back in his cage I noticed that not just his shed came off but there are a couple of small areas where the entire skin itself came off revealing the white flesh underneath. There also appears to be spots of blood. My question is, could the be due to the current sensitivity to his flesh and picking him up with the broom resulted in pulling it off or could this be something else? There are no traces of mites, or weezing or other signs of disease, any information would be helpful!
