Up to 84 percent of people worldwide experience low back pain during their lifetime, according to the authors of a February 2012 review article published in the journal "Lancet." Sciatica is a common form of low back pain that often radiates into the legs.

Neuropathies are disorders or dysfunction of the peripheral nerves--those outside the brain and spinal cord. Hereditary diseases, trauma, toxins, infections, medications and systemic and autoimmune diseases can all cause neuropathy in which sensory and motor functions -- muscle movement and strength -- can be impaired.

Neuropathy, also commonly known as peripheral neuropathy, is a condition in which nerves that carry information to and from the brain and spinal cord become damaged. Symptoms of neuropathy typically include numbness, pain and tingling in the hands and feet.

Patients with neuropathy experience chronic pain and tingling, and acupressure may provide some relief. Neuropathy results from nerve damage associated with a traumatic accident, infection, metabolic disorder, such as diabetes or exposure to toxins.

A tingling sensation can occur with numerous medical conditions. Any changes to nerve function can lead to unusual sensations, including tingling, burning, pins-and-needles, itchiness and numbness. It is common to experience a combination of these sensations.

Damage to the nerves of the peripheral nervous system is referred to as peripheral neuropathy. The peripheral nervous system is a network of neurons that connect the spinal cord and the brain to the rest of the body.

Neuropathy is nerve damage that can result in pain, numbness or tingling. Injury or vitamin deficiencies usually cause this condition. According to MayoClinic.com, a number of medical conditions, including diabetes, may lead to foot neuropathy. Exercise can help reduce pain from this condition.

Peripheral neuropathy is a condition that affects the nerves outside of the brain or spinal cord. It can cause changes to sensation, movement and involuntary functions. Pressure on the nerves can cause peripheral neuropathy, as can certain conditions such as Charcot-Marie-Tooth disease, an inherited disorder.

Most people don't think much about their feet until they hurt or give you trouble. Burning and tingling in the feet usually signals nerve irritation that may be due to injury, infection or other medical disorders.

Your spine is made up of a column of bones stacked on top of each other. Discs provide cushioning between each of these bones. Sometimes discs may bulge -- move out of place -- and put pressure on nerves that exit your spine. Symptoms are specific to the level of the bulge.

Pain from a pinched nerve can make daily activities difficult. Shoulder exercises can decrease pressure on a pinched nerve.

The carpal tunnel is a narrow pathway on the palm side of the wrist, through which the median nerve travels. This nerve can be compressed within the tunnel by overuse of your wrist and fingers or by trauma to your hand. Nerve compression can lead to pain, numbness, tingling and weakness.
