PF can become really nasty, if you don't take care of it right away. I used to run marathons, and I did get PF on a couple of occasions. Arch support is very important. Do not get out of bed without your orthotic in a shoe. If you get out of bed and step, you will just re-tear that ligament and the process will continue to get worse. The ball rolling is excellent, and just taking it easy until healing begins.
