Stone day 2

My left side is kinda feeling like I got rabbit punched (not to self: why is a punch to the kidneys called that?) a couple days ago. Yes, I have been punched before. I went to work out earlier today - ended up just doing stretches in the sauna. The side stretches were not too bad. The pain should recede in a day or so until the stone gets to my bladder and tries to get out; that is going to hurt a bit and probably bleed somewhat.
