The Shedding Process

[JLC]

First, does shedding cause them discomfort like itching, burning, pain, like sunburn symptoms? Second can a bad shed cause fatal problems?

First of all...I don't think anyone could ever say. Snakes are notoriously close-lipped about such matters.

Second...it's conceivable that multiple stuck sheds, encircling the body, left over a very long period of time might eventually cut off enough circulation to cause death. But I've never actually heard of that happening.
