I have no idea how but my snake has got himself stuck and he is hurting himself trying to get out, I see pink flesh coming out of his belly as he is trying to rip out of it. I have tried putting water base lubricant but nothing is helping, i think he has caught himself on the inside.

Any suggestions? I am desperate, I cant take him to the vet till the morning.
