Yup, you beat me to it. What you're up against in a starved snake is that the skin gets very weak, because the body prioritizes internal organs over skin when food
is lacking & the skin may never fully improve: it tears very easily. Those fluid pockets may appear normal but then tear open & need long-term care before slowly
improving. (prescription Silvadene cream is best on the open wounds) It's possible to keep this snake going, but euthanizing might be kinder? It's hard to say.
