Peripheral neuropathy, a result of damage to your peripheral nerves, often causes weakness, numbness and pain, usually in your hands and feet. Peripheral neuropathy can affect a range of different nerves, so it can impact a variety of locations in different ways. It can affect a single nerve or several nerves at the same time.
Peripheral neuropathy symptoms can range from mild to disabling and are rarely life-threatening. The symptoms depend on the type of nerve fibers affected and the type and severity of damage. Symptoms may develop over days, weeks, or years. In some cases, the symptoms improve on their own and may not require advanced care. Unlike nerve cells in the central nervous system, peripheral nerve cells continue to grow throughout life.
The outlook for peripheral neuropathy varies, depending on the underlying cause and which nerves have been damaged. Some cases may improve with time if the underlying cause is treated. However, in some cases, the damage may be permanent or may get gradually worse with time.
