From what can be seen of the head end in the first pic, the snake looks in reasonably good condition. I would be loathe to make judgements based on the second photo due to poor lighting and the distortion caused to its body shape by being wrapped across the frame of the screen door for support.
As was mentioned, the “skin worms” referred to are a stage of an initially aquatic tapeworm that are picked up by eating frogs (which makeup about 80% of the diet in nature). This second stage of the tapeworm moves from the gut to the skin (and occasionally muscle) tissues and encysts there. When the snake is eaten by another animal, usually mammal, the worms will develop into their adult stage and start producing eggs. So this stage can be thought of as essentially a resting period, awaiting the final host. Adult CTS can often carry 20 to 30 of these cysts with little affect on their general health.
I know as kids we used a knick from a razor blade, dipped in a bit of metho first, and used pop the contents like a pimple. The cuts healed without any dressings other than a wipe of a metho soaked ball of cotton wool and the snakes seemed none the worse for the experience. They certainly recovered OK. I have seen similar bumps on RBBs, though not as many, and the same treatment revealed similar looking worms. I would imagine that following a clean with a disinfectant, that an antibiotic for the skin held there by a dressing would be the way to go theses days.
My understanding is that removal of these parasites is more for aesthetics than the health needs of the animal. Should anyone know otherwise, I would appreciate hearing about as specific information regarding CTS is scant.
