Sensory Neuropathy is the deterioration of the nerves in the leg that detect sensations such as heat, cold, or pain. Damages resulting from sensory neuropathy is most often caused by repetitious injuries that can't be felt. Continually walking with pressure on one part of the foot, foreign objects in the shoe, tight fitting shoes, or walking barefoot may result in corns, calluses, and sores, leading to ulceration and infection.
