Sounds like a trip to the vet is in order, since you'll be hard pressed to find a reptile Vet here that will diagnose and treat your animal online. Keeping them on paper towel is a start.

Why is the enclosure not secure? If this is a known common problem, what have you done to remedy the situation? I would hate to hear that your ball python escapes again, and something worse were to happen because you neglected to ensure the cage was properly secured when closed.

Giving us a very detailed description of your enclosure can help us give you ideas on how to make sure the snake does not escape, and that all of it's needs are being met husbandry wise.

Here is a link to this forums care sheet, please review to make sure you are providing correct husbandry.
