I tried attaching an alligator's leg to mine. It didn't work...?

I recently got advice on here about how to perform this surgery and it didn't work out how I thought it would. After sawing off my leg (a bit above the ankle) with the help of a friend, I tried to attach the nerve endings and sew the frozen (well then thawed) alligator leg onto it. It was extremely painfully, like the most pain I have ever felt before, but after a little while I got used to it. After sewing it on successfully, I paper mached the entire thing and basically spent the next two weeks just sitting around in pain. After 16 days, I removed the paper mache to find my leg and the alligator leg all discolored and strange looking. I couldn't move the alligator leg at all. I was the most disappointed I have ever been in my entire life that it didn't work out right. Is there any hope for me, my leg, the alligator leg (very expensive) or this entire thing to still end up working out? Also, I am still deciding on whether or not to get my friend to drive me to the hospital. PLEASE HELP!!!
