A pinky mouse is MUCH too small a prey item. I bet the mouse is stuck in the throat and snake can't get it to go down right (why...I'm not too sure). I've not had this problem and I'm not sure what to tell you except try to call a herp vet and ask what they would do and if you need to bring the snake in. I bet that mouse is already decaying and if the snake eats it, then it will probably make the snake sick and cause it to regurg.
