My doctor (a well respected doctor who attends to several Chicago Bulls) insisted that activity could not harm the site or hamper the healing process after the surgery. At worst, it would cause pain, but that was supposed to be fine if I wanted to endure it. In fact, activity is supposed to be necessary to promote proper healing.
I was worried about healing and attachment that might take place at night, while the foot was pointed down and the fascia slackened. So I wore a night splint for a couple of weeks or more to ensure that the tissue would form with enough slack for normal extension.
I went back to running (as I was supposed to be able to do), and the problem is as bad as ever. I stretch properly. I'm not overweight.
So I would go with surgery anyway, because there really isn't anything else to do. I tried every other tactic except acupuncture, and it was a total waste of time. But don't expect success. If the success rate is 90-95 percent as claimed, then I'm really pissed at being in that 5 percent.
I wish we understood nerve connections well enough to simply sever the ones that serve the fascia.
