As the nerve endings become damaged, the brain scrambles to make sense of the goofy signals from the feet, legs, hands, face, or wherever the damage occurs. The brain finally settles on an interpretation of the signals as pain: aching pain, burning pain, stabbing pain, creepy crawly pain, electric pain, usually all of those.

Then the areas of the brain that get the signals from the damaged peripheral area and the main nerves that carries the signal to those areas of the brain become hypersensitive to any stimulation from the area. That is what neuropathic pain is; it starts in the feet or hands or wherever, but its even more so in the brain and main nerves to the brain.

Healing is a two step process. First, stop further damage to the peripheral nerve endings. Know that the damaged nerve endings will continue sending inappropriate signals until they heal, regrow, or die off (experienced as total numbness in the area).

Second, train the brain and main nerves to settle down. Anticonvulsant drugs help, but in themselves don't retrain the brain. They just put a partial lid on the hyper-sensitivity. To retrain the brain and main nerves, I know of only two things that work. Both are rhythmic, and impose order and proper function to what is chaotic. The first is exercise: walking (left right left right, etc.), swimming (up down up down, etc.) etc. The second is electro-stimulation with a pulsed micro-current, about 5-8 pulses/second.
