Foot injuries are especially nasty. I once had a tooth punched out, and it hurt less than when I broke some bones in my foot.
I imagine it's a nerve thing, feet are full of them. I will say that it is important to stay on top of a foot injury, as it can lead to many poor outcomes if one is not vigilant.
I have stepped on many a tack, and it never becomes pleasant.
My mom used to have me lift her up to help with back pain, but one day there was a crunch. Broken ribs are annoyingly difficult to manage.
