So sorry for your experience I hope you are able to recover soon!

My experience with plantar fasciitis is that it is a long recovery. It takes time. I kept a tennis ball under my desk and by the couch so that I could roll it under my foot throughout the day. I also did a lot of calf stretching. A tight calf can really aggravate PF. I believe I took 2 weeks off of running altogether while I focused on stretching and rolling--several times each day.

Then I slowly started walking and jogging, keeping my miles low. I didn't start running distance (over 4 miles) for 3-4 months. But I was able to heal the PF and haven't had an issue since (that was 2 years ago).

I also know some people that have had surgery for PF and are back to running. But in my opinion, if can rehab myself, even if it takes 5-6 months of reduced mileage or even eliminating running altogether in favor of cycling, walking, swimming, etc--it is well worth avoiding surgery.
