Neuropathic Pain

Neuropathic pain is a chronic condition caused by damage within the nerve fibers, resulting in the delivery of incorrect signals to the brain. Neuropathic pain, a response to injury to the central nervous or peripheral nervous system, usually causes tissue damage. What makes neuropathic pain so difficult to treat is that it is not only chronic and severe, but unresponsive to simple analgesic relief.

In addition to stabbing, shocking or shooting (not aching) pain, patients may also experience numbness, tingling and weakness in the affected region of the body. They may also, because of exquisite nerve sensitivity, experience allodynia (pain provoked by gentle stimulus) or hyperalgesia (excessive pain provoked by a slight pain stimulus). A further addition to patient misery with neuropathic pain can be the insomnia suffered because of unremitting pain.

Causes of Neuropathic Pain

Neuropathic pain may occur as a result of several different factors, including surgery, certain diseases and underlying conditions. These may include disorders that cause nerve compression, such as:

Neuropathic pain may also be caused by diseases, such as those listed below:

Other miscellaneous causes of neuropathic pain may include chemotherapy or the ingestion of toxins, problems with facial nerves, like the trigeminal nerve, or phantom limb syndrome in which pain is experienced in a non-existent limb after amputation. In certain cases, nutritional deficiencies, especially a lack of sufficient vitamin B6 or B12 may result in neuropathic pain.

Treatments of Neuropathic Pain

There are a variety of treatments for neuropathic pain, depending on its cause. Where neuropathic pain results from a compressed nerve, as when a patient suffers from carpal tunnel syndrome, if more conservative methods are not effective, surgery may make a marked difference.

Where an underlying disease or condition is responsible for the neuropathic pain, more efficient treatment of the underlying condition, for example diabetes or alcoholism, may alleviate the problem. Other treatments of neuropathic pain are divided into two basic methods.

Because neuropathic pain does not respond well to standard treatments, and because it may progressively worsen, a combination of therapies often provides the best treatment results. Since chronic pain is extremely stressful, and since stress tends to exacerbate pain, psychological counseling is often recommended as part of the treatment plan.
