After the pain went away, I had an odd numb sensation
on a patch of skin about two inches wide by 4 inches long
on my skin where I hit my shin. I couldn't tell when someone would lightly brush my skin, but I could feel when someone pressed hard. Along with the numbness, occasionally I would get a very intense itching, but not matter how much or hard I scratched, the itch would not go away and I would have to wait it out.
