I don't think so. Pinched nerves can cause tingling, numbness, and pain, but oscillations like this are due to a problem in central programming of movement, or in this case the failure of the system to inhibit over-movement trying to stay in position. It is the spinocerebellum that does this inhibition of reflex oscillations.

I have a second theory about what is happening. My mental fuzziness and physical changes could be due to my repeated concussions, the two most severe ones being 1) from running the 20 foot waterfall Gorilla upside down and hitting my head twice on that bad run and 2) the 35 mph over the handlbars bike wreck of just two years ago.
