Replying to Gnarly injuries

So I ripped out the muscle that connects your pointer finger to your thumb jumping a fence the other night. It was mad deep and I musta lost like a gallon of blood. The muscle was like sticking right out of my hand since I severed it. So what I'm asking is, has anyone done something stupid like this and gone it without stitches. Its been like 3 days and I dont want to go to the doctor but it's like still bleeding, its like the grand canyon, and it gets ripped open if I try to use my hand for anything.
