I had a huge bruise on my left hand from the IV. It lasted for about a month and it was very painful and swollen! I feel your pain! Too bad there's nothing u can do about it, most people get it. As far as driving goes, I was pretty sore so I didn't even attempt driving for a week after, and when I did I was still pretty sore and going over the bumps hurt! ;) As long as everything else is okay, these are minor things that will heal in time.... I like the idea of bringing the patio chair inside, but it must not be very comfortable? Truthfully nothing was comfortable for the first few weeks! Esp since I couldn't sleep on my side. Best of luck.
