In order to begin to answer this question I have to explain a bit about fascia. Fascia is soft, connective tissue that runs continuously throughout the body. (We will forego the discussion on duramater for now), Fascia wraps around and criss-crosses EVERYTHING. It’s like a stretchable fabric- somewhat stretchable in some directions. Looks kind of like a spider’s web. And as I said, it is CONTINUOUS throughout the body- lliterally. For example, some of the fascia that starts out on the left side of the head ends up on the outside of the right ankle. When there is a “kink” in the fascia in one or more places, the restriction can transfer to a completely different area.
So. It IS possible that a sore, stiff neck could have started from rolling the opposite ankle. I know that is hard to imagine but it is the way it is. It’s hard to imagine that as I work to get the neck unstuck your plantar fascitis can release but this is a very real possibility. So, when you come to me for a neck problem and I am working on your tailbone- don’t think I’ve lost my cookies- just remember it’s all connected!
