So in the middle of last month I accidentally jammed a running drill into my thumbnail. It hurt like a mother. It's left a bruise, which initially was touching the base of the nail. I noticed today that the bruise it has left has actually cleared the lighter portion of the nail near the base, and is much close to the middle, but it hasn't changed in appearance much. It appears to be advancing towards the end of my finger as the nail grows. It doesn't hurt even when pressed, so I'm not too concerned about, but thought that it was curious.
Is it normal for a bruise to grow out with the nail?
