Okay, an update. My EMG indicated chronic nerve issues at L5-S1 and possible tarsal tunnel syndrome as an explanation for the loss of power in my foot and lower leg.
Just got back from a neurologist, and it turns out to my surprise, that the condition I have is S1 radiculopathy, which means the nerve root at S1 is not firing to the gastroc. So, I had some sensation in the foot, but was able to sometimes stand on my toes, but during walking or running, or for flat-footed toe raises, getting power to left my heel was just about impossible. The reason is the gastroc is what is doing the majority of the work. Colloquially, this is a pinched nerve condition, so I'm taking a table steriod and another medication, which has only a slim chance of working. I'm not exactly sure what the next step is since the neurologist is writing up his report which I presume the orthopedist is going to review in designing the next treatment step.
I am relieved to know precisely what my issue was, but it was odd, to me, that the problem all along with the loss of power was not in the foot at all, although during stride it felt like it, but was instead the gastroc not doing it's job of producing power and push off 'independently' of the foot.
Now, anyone know anything about S1 radiculopathy treatment/pinched nerve treatment?
