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 rare condition 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.
Hand pain has many causes, including injury and disease. Fortunately, many of those causes can be treated and the symptoms eased.
Here are some of the most common conditions that cause hand pain.
De Quervain's tendinitis. This is also known as de Quervain's tendinosis. It causes pain on the thumb side of the wrist.
The pain may develop gradually or suddenly. It can travel the length of the thumb and up the forearm. If you have de Quervain's tendinitis, movements that can be painful include:
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. The doctor may also request both blood and nerve tests.
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. Effective management of the condition can also help prevent further nerve damage.
Unfortunately, neuropathic pain often responds poorly to standard pain treatments and occasionally may get worse instead of better over time. For some people, it can lead to serious disability. A multidisciplinary approach that combines therapies, however, can be a very effective way to provide relief from neuropathic pain.
