Nerves in general, especially nerve roots, are not getting actually “pinched” as in getting a kink in it, but instead, most of the situations people are describing as a pinched nerve, is actually a situation in which there is a pressure increase (or a partial pressure increase) on the nerve. From experiments in nerve physiology, we know that nerves do not respond well to increase pressure on them, and indeed, even a relatively small increase in pressure can have dramatic effects and in causing nerve pathology.
