QUESTIONNNNNNNNNNNNNNNNNNNNNNN…

I banged my hand accidently into the corner of a chair accidently because I was stretching, and I banged the left side of my left hand and it was hurting a lot, but that happened two days ago and now my entire left hand (not arm) is still hurting and when I pick up something heavy I can do it with my right hand but my left hand really hurts. And you know when you put your hands on your hips, you do it two ways; one way is when your thumb is in front and the rest of your fingers are behind, and the other is when your thumb is behind and the other fingers are in front. So when I put my hands on my hips with my thumb behind, my left hand really hurts. It feels like that threw my nerves I think. Is this just from the bang and will it get better because it's scaring me.
