Josh, I hope from your description of tingling that you don't wind up with nerve damage from this. I have a big toe with weird sensations from a weird accident where a thin metal rod got hooked in my toe, but that's another story. It sounds like you'll recover fine, but you do realize of course that you'll have a much bigger scar and take a lot longer to heal. I had a similar incident once where my palm was sliced open while I was in Mexico. I was nearly broke, didn't relish the thought of getting medical treatment in a small Mexican town, and put off getting anything done until I got back to Arizona that night. The ER said it had been too long for stiches, but luckily I actually had first aid supplies with me on the trip and it healed fairly well.
