I appreciate all the well wishes. Seriously guys, it really means a lot to me.
I was discharged from the hospital a couple of days ago, and am at home now. Had to have a small surgery where they went in and evacuated the hematoma (basically suck as much of the clot out as they could without disrupting anything else). A few days later they were able to pull the tube out of my kidney. My urine will be pretty dark for the next 6 weeks or so while everything heals, but there should be no long term effects.
No need for surgery for the arm - I've got another 7-10 days in a cast, then I can likely be put into a splint and sling while I work with physical therapy. Ribs hurt, but are much better than they were. Really the most annoying part right now is the effects of the concussion. Still lots of headaches, still sensitive to light, stuff like that. Really there is no telling how long that will last.
I'll be in and out as I am able. Thanks again for the support.
