How long does a steroid shot last though? Is that something you will have to continue to do, if you don't try surgery?
I bought a TENS unit for PF. I haven't used it as often I as should, so I can't say if it works or not. Matt swears by it though. He says without it, his PF would be so bad, he couldn't walk.
I just got my ultrasound unit yesterday and used it last night. Just like the TENS unit, that was a weird experience. I could actually feel the pulsing waves going into the bottoms of my feet, and when I placed it certain places, it was kinda painful to quite painful in other areas of my foot, like the top of my foot. Have you thought about getting an ultrasound unit. You may have to have someone else use it on you, but I understand they are great for healing the body. Check them out anyway.
I hope you do well through this, and let me know how you progress.
