i cut my forearm on a door all the way to the bone from my wrist to me elbow. the doctor said The same thing to me, no nerve damage, no cut tendons, i was so lucky that i didn't even cut an artery, but the opposite side of my arm has been numb for about two weeks, [ever since the accident] and i can't find anything about it on the internet. i'm worried that it will stay this way for the rest of my life, i'm only 17 after all. but i'm trying to figure out how to gain more feeling back faster. but i had 4 stitches in my finger too, it is numb on the outside but when i squeeze it then i feel pain, if you feel in pain on your finger, it will eventual return to normal. it would just be the outter skin that's numb, which is normal.

Update: It's been a few months since this occured and I'm happy to say I now have feeling in my finger again. Apparantly the nerves will heal themselves eventually (at least they did in my case). Hopefully the same happens for you as well!
