Neuropathic pain symptoms are often unpredictable, and vary significantly from person to person. Pain may be triggered by a specific stimulus, or occur on its own. In the case of a sudden impact, the area surrounding the site of the trauma may be affected in addition to the immediate area.
Some people have constant pain, while others may experience pain that occurs on and off.
Neuropathy May Limit Daily Functioning
Neuropathic pain often makes movement painful, leading an individual to limit mobility. Being sedentary can cause muscles to weaken, further restricting physical functioning. Many people with neuropathy are unable to work.
Back pain or other pain caused by neuropathy is typically described in the following terms:
- Severe, sharp, electric shock-like, shooting, lightning-like, or stabbing
- Deep, burning, or cold
- Persistent numbness, tingling, or weakness
- Pain that travels along the nerve path into the arms, hands, legs, or feet
Skin in the painful area may be discolored, appearing more pink or red than usual. In some cases, the skin may have a blue or mottled appearance. Changes in color are usually related to changes in blood flow. Some individuals also experience swelling.
Many people with neuropathic pain also experience sleep difficulties and depression, both of which can increase the perception of pain.1 A multifaceted pain management approach may be beneficial to address all aspects of the person’s health.
Unusual Sensations in Neuropathy
People with neuropathic pain may experience sensations in unusual ways, such as:
- Hypersensitivity to light touch that would be barely noticeable to others, is known as allodynia. The feeling of clothing against the skin, for instance, could trigger a reaction.
- Hyperalgesia is an extreme sensitivity to something slightly painful to others.
- An unusually low sensation to hot or cold is called hypoesthesia.
- An electric-shock or pins-and-needles feeling when there is no contact, a known as paresthesia.
Sensory tests may be conducted to see how the individual responds to different types of physical contact.
Treatment for Neuropathic Pain
Electromyography and nerve conduction studies, blood tests, and diagnostic tests such as magnetic resonance imaging (MRI) may be used to determine the cause—or rule out a potential cause. Test results can be helpful in finding the most effective therapy.
If no underlying cause of the pain is found, treatment typically emphasizes pain relief. There is no single medication that eliminates the symptoms of neuropathy, but a combination of medications and treatments may be helpful Care from an interdisciplinary pain management team may be advised for individuals with neuropathic pain.
