Diabetes can damage the nerves and cause a complication called neuropathy. This generally begins as loss of sensation in the toes, and possibly fingers. Eventually, the neuropathy can move up the person's legs or arms. Nerve damage results in decreased ability to feel pain, pressure, and extremes of temperature.
