Nice progress man, I remember those days. Of course the swelling and pain in your muscles and joints are normal from lack of use, but once you start therapy that'll reduce quickly.
It is possible to drive a clutch with your right leg, just takes a bit of practice, I know cuz I did it, but if you're not comfortable hopefully you'll find a nice cheap beater.
BTW, I've got 3 sets of crutches and 2 canes (1 carbon fiber) laying around in case you need a backup set, but got rid of the chair a long time ago.
