Wow! What a story..... To be certain that you get my resonse, I will copy this and paste it at your site as well. I am sorry for the late resonse... I have been away from the site for a while.
Your situation sounds very muck like mine. I mean... my leg was pretty much destroyed but the accident seems like mine. I know what you mean when you say blure and when you tried to get up and the leg did not work. What a feeling! Your Dad seems pretty hard core lol. It must have been very painful on your trip to the hospital. The good thing is that you did not need surgery.
When will you start P.T.? I think that I start mine in about two weeks.
