Just thought I would share my experiences as only people suffering can appreciate the despair of this condition. I started with it 30 years ago after working on hard floors whilst wearing poor quality boots and also had been doing a lot of calf raises as I tried to get fit. My right foot went first then my left started hurting one day as I walked on bobbled tiles in the swimming baths. I suffered terribly for three years until it had just about gone, after changing my job so I was not standing any where as much.
Then I made the biggest mistake of my life as I took up the offer to have surgery thinking this would put an end to it once and for all. After three weeks in plaster I was in a different sort of pain now with the top of my foot hurting as well and also had inflammation on the plantar as opposed to sharp pain under my heel. Over the years it gradually improved to a point where I did not even think about it , then Bang! It returned without warning 6 months ago and, so I am back at the beginning again, with a monumental mountain in front of me again as it seems no improvement in treatment has been forthcoming.
The side of my feet, (underneath) are also now affected and standing in the same position after just a few minutes is close to distressing.
Hopefully my extreme experiences can help others evaluate the recovery time they might be looking at without taking drastic action as I did all those years ago.
