Black Toesday

Finally! It's not where it's supposed to be, but it was killing me where it was.
It took some effort and a little pain but it finally came off. It was painful.
man... this thing was bugging me for a while.
It was hanging on for dear life and wouldn't let go.
Runners get this a lot.
I even went swimming yesterday and hoping that the water would soften the area so that it would come off easier.
Instead the flutter kick motion of my legs was making it go up and down and it was bothering me the whole time I was swimming.

Now I finally got it off. It's like pulling a tooth. I was ready to go get some local freezing done.

Can you guess what it is?
