I have plantar fascitis. I started wearing New Balance shoes, did some exercises to help and stayed off of my feet for a long time. It helped me a lot.
I take walks but I do watch for symptoms popping up and then quit walking for awhile.

I was told years ago that the tendons in the back of my legs were too short when we lived in New Mexico. I went to the ER and the Dr. there told me this and it is one of the causes of plantar fascitis.

I am sorry you are having these problems. It's possible you have both.

I would find a good Pain Management Dr. or see an Anesteologist for the possible RSD.

I didn't know you could have surgery for the PF. Did you have any PT first?
