tingling/plantar fasciitis for 3 years

The following is a current description of my symptoms and what I am going through. OnePodiatrist said that he knows of nothing that can help. I believe I have plantar fasciitis for three years. I have been very proactive. At first I had pain in my arches very in the mornings and throughout the day. I have kept off my feet for the most part. I do some recumbent biking roughly four days a week over the last few years using my heels, but know I feel that too is putting pressure on the problem areas.
I stay off my feet most of the time. I have had several series of injections, two different types of orthotics, three different podiatrists, a lot of anti inflammatory, taping, stretching, and night splints. I have had two nerve tests and they came up normal.
I don’t have localized pain. I rarely have pain. When I do have pain, it is minimal. When I first started having this, I did have a lot of pain in the morning, mostly in the bottom part of the arch.
If I now pushed myself on my feet, I am confident the pain would come back. If I do some sort of activity like golf(using a cart), then they might tingle more for up to three days and they feel as if they have swelled up a bit. My balls of my feet tingle most of the time, more when I am on them and a little when I am sitting after some sort of walking.
The little amount of pain that I have is in the arches. The pain is extremely minimal, but I do not use my feet that much. In my opinion, it is like my plantar fascia is like a piece of rubber that has been over stretched and worn out and it is sore. So my feet get achy with use. I would say it is not in the heels. It is as if I can feel the plantar fascia and it is sore. They do feel good after a night of night splints. I can say that I believe the area of concern is in the arches about a three to four inch area. It is difficult to really know since the tingling is in the balls of my feet. Do you think extracorporeal shock waves could help?Do you have any other suggestions?
