ok just to let you know, i do have a vet appt tomorrow, but i want to know what to expect, and if there is a chance (however slim) that i dont need to take him in...

i took my snake out today, and immediately noticed he was about to go into a shed. (his scales on his back felt funny and his eyes were blue, which are his telltale sign of shed.) however, his underbelly felt weird, so i flipped him over, and noticed his scales looked REALLY weird. they were brown instead of their normal pink, and there were little flecks of blood here and there under the scales. they were starting to bubble up too in places. i got a few pics jut to give a good idea of what i am talking about. has ANYONE ever seen a snakes underbelly look like this? im really worried about him. hopefully its just further in the shed than i thought and i dont need to take him to the vet, but of course i will if it needs to be done.
