Plantar fasciitis keeps on

I've been waking up a night this past week or so needing to stretch my legs in bed. I'm not sure if this need is what wakes me up but it is persistent. Yet if I stretch with my toes pointed I have been getting a hyper-contracted calf muscle that is so painful it sits me right up in bed wanting to scream. The pain is so incredibly bad and it is very difficult to get it to subside that I'm becoming afraid of it. Last night it started in my left calf; initially I have experienced it only on my right side. A little research online suggests this is probably a result of my plantar fasciitis. And, as I have been increasing the number of days I walk to town again, and working more where I have to stand all day, my feet have been hurting more. The simple solution is to stretch more, especially before I walk, and probably not to walk so far. I keep thinking that September will be a busy month for me and I will have to cut back on the amount of time I spend walking. Perhaps the muscle contractions will decrease as well. I guess I haven't given the plantar fasciitis time to heal since my camino. It is hard not to keep on walking. I can't seem to find a suitable balance.
