Review for Plantar Fasciitis

I have all the PF symptoms but I also have arch and ball of the foot pain, along of course heel throbbing. My grandmother and mom had foot issues and I do believe my problem is part heritary. This I have arrived on my own conclusion. I've seen 3 podiatrist and they all believe that I PF goes away, except mine doesn't. As I age I wish I could exercise more, go on walks w my dog etc. I find my self saving my feet for work (I teach kindergarten). I do feel relief when I have a week of more of low activity but that's not healthy either.
