What causes "phantom" pains and how can you get it cured?

Nerves. Phantom pains occurs after an amputation and is related to the nerves being cut during the amputation. It is unclear exactly why they occur but one of the possibilities is that the brain "memorized" the pain so it is still present even when the part of the body is removed. It usually improves with time after an amputation. If it does not meds to treat nerve pain are helpful.
