Like you were told in your other thread: "Vet ASAP".
Continuing to wait increases the likelihood that the vet won't be able to help your snake, and it probably increases the cost if they can. If that was my snake I'd be looking for an on-call emergency service (wouldn't have waited three days with a prolapse either...). You need to get that snake to the vet as soon as you possibly can; tell them it's an emergency and you're willing to wait or drop the snake off before work or whatever it takes to get him seen as soon as possible.
