Walking again

Last Thursday I finally got my cast off. I was so relieved. I thought I would be able to drive once I got it off and was excited....Well that didn't happen. Although the ankle bones are healed there is still much tenderness on and around the joint. Lets not forget my achilles and calf muscles haven't been stretched and are extremely tight that I I am having a hard time walking. I got my big boot and trying to manuever with that is taking some getting used to. As the days go on, I am getting more mobile. At first I was using my crutches then went to a cane yesterday and today nothing. I need to keep adding heat to my joints to increase the flexibilty. I have 3 more weeks and then I will see what happens next...therapy?
