I have had lots of minor training injuries. Knock on wood, I've only had one serious injury -- my torn ACL last year. I am currently suffering from one of my oddest training injuries: I have mat burn on my toes.
We were practicing kuzushi in newaza last night. We started in a kneeling position and pummeled for position, grappling to feel the loss of balance, or the overcompensation in the other direction to fight a push or pull. Somehow, in the midst of this, the tops of my toes got a nice mat burn and I rubbed off the outermost layer of skin.
I was uncomfortable last night, but didn't think much of it. This morning I staggered into the shower and as the hot water hit my feet, I had a very literal rude awakening. Right now I'm looking at the thin scabs on my toes! Very weird.
Do they make sock rash guards?
