I hurt my hand 4 weeks ago when I punched a hard surface (not expecting any sympathy, it was an act of drunken idiocy...). At first I thought I had sprained my wrist as the pain wasn't severe and I could move my fingers and wrist without much issue. However after 4 weeks, I still have a pain around the knuckle of my index finger and the bone that runs up to it when pressure is applied (for instance, during a hand shake). I still have full range of mobility with my fingers and wrist with no pain.
