Is my snake going to die?

I have a 2 year old western hognose and i just fed it a very frisky mouse. It grabbed the mouse from the bottom which allowed the mouse to bite it repeatedly. The first time i can tell was most like the worst bite because 1) there is an open scar on my snake 2) when bitten, a yellow/venom-like liquid squirted out of the cut. My snake is acting just fine, but the cut doesn't have anything oozing out, it literally looks like a papercut but it's more obvious. I am extremely worried because this has never happened to me before. What do i do???
