Neuropathic pain is a complex, chronic pain state that usually is accompanied by tissue injury. With neuropathic pain, the nerve fibers themselves may be damaged, dysfunctional, or injured. These damaged nerve fibers send incorrect signals to other pain centers. The impact of nerve fiber injury includes a change in nerve function both at the site of injury and areas around the injury.
One example of neuropathic pain is called phantom limb syndrome. This occurs when an arm or a leg has been removed because of illness or injury, but the brain still gets pain messages from the nerves that originally carried impulses from the missing limb. These nerves now misfire and cause pain.
Causes of Neuropathic Pain
Neuropathic pain often seems to have no obvious cause; but, some common causes of neuropathic pain include:
- Back, leg, and hip problems
- Facial nerve problems
- HIV infection or AIDS
- Multiple sclerosis
- Spine surgery
- Symptoms of Neuropathic Pain
Neuropathic pain symptoms may include:
- Shooting and burning pain
- Tingling and numbness
Diagnosing Neuropathic Pain
To diagnose neuropathic pain, a doctor will conduct an interview and physical exam. He or she may ask questions about how you would describe your pain, when the pain occurs, or whether anything specific triggers the pain.
Neuropathic Pain Treatment
Some neuropathic pain studies suggest the use of non-steroidal anti-inflammatory drugs, such as Aleve or Motrin, may ease pain. Some people may require a stronger painkiller, such as those containing morphine. Anticonvulsant and antidepressant drugs seem to work in some cases.
If another condition, such as diabetes, is involved, better management of that disorder may alleviate the pain.
In cases that are difficult to treat, our physicians may use an invasive or implantable device to effectively manage the pain. Electrical stimulation of the nerves involved in neuropathic pain may significantly control the pain symptoms
