The countless nerves in our body send signals to the brain including the signal for pain. Pain has a very important function of protecting our body against external damage. But this signaling does not work properly in people with nerve pain. They might get the sensation of pain but without understanding its cause. Nerve pain, which is also known as peripheral neuropathy or peripheral neuritis, usually occurs due to some physical damage or disease.
Cancer and other tumors can cause neuropathic pain as the tumors tend to press on the surrounding nerves. Chemotherapy drugs can also cause nerve pain as they can damage the nerves. One of the first symptoms of a person suffering from HIV is nerve pain in the hands and feet. A diabetic person is prone to nerve pain as high levels of glucose in blood can damage the nerves. A person can suffer from severe nerve pain if he/she suffers from postherpetic neuralgia. Nerves can also get severed, compressed or crushed due to some physical injury and this may cause nerve pain.
The treatment for nerve pain depends on the age of the patient, underlying cause, costs and potential side effects. A person will have to undertake treatment for the underlying disease in such cases. However the different treatments options for nerve pain include use of topical treatments, anticonvulsants, anti-depressants, pain killers, electrical stimulation and, in some cases, surgery.
