If you've been dealing with plantar fasciitis long enough, someone has probably suggested a cortisone shot. Maybe your primary care doctor. Maybe a podiatrist. Maybe a well-meaning friend who swears it fixed theirs.

You've foam rolled it. You've stretched it. Maybe you've had someone "release" it on a table. Maybe you've taken two weeks off, laced back up, and felt it come back by mile three.

It's one of the first questions I get from postpartum runners. And the honest answer is: it depends on a lot more than how many weeks postpartum you are.

The six-week clearance is real. It's also incomplete.

If you've heard of shockwave therapy, you have a rough idea of what it means to use technology to restart healing in tissue that has stalled. EMTT works on a similar principle - but it reaches places shockwave can't.
