Mapping the nerves: There are several nerve-centers (hubs) of nerves crowded into our feet (and hands). They were useful for our ancestors' (barefoot lifestyle). The networks incl some w/ connections to distant parts/organs. So, it origin can be elsewhere, but a serious foot massage can help. See accupuncture/pressure charts - reflexology, too. Western neurology or orthopedic pros may also help. Wear proper shoes!
