When most people think of itching, they often associate it with skin conditions like bug bites, rashes, or allergies. But what happens when you feel a persistent itch and there’s no visible cause? This could be a sign of neuropathic itch, a type of itch that originates from the nervous system rather than from the skin itself.
What Is Neuropathic Itching?
Neuropathic itch, also known as neurogenic itch, is a sensation caused by nerve damage or dysfunction in the nervous system. Unlike an itch from a skin condition like eczema or hives, this type of itch is triggered by problems in the nerve pathways that send signals to the brain. This can result in a chronic, sometimes unbearable itching sensation, even when there’s no physical cause like a rash or insect bite.
How Does Neuropathic Itch Happen?
The sensation of itching is typically a protective response by the body, urging us to remove irritants from the skin. However, in the case of neuropathic itch, something goes wrong with the nerves that carry sensory signals. When the nerves are damaged or misfire, they send abnormal signals to the brain, which are interpreted as an itch.
Some common causes of neuropathic itch include:
- Nerve damage (neuropathy). Peripheral neuropathy or nerve damage caused by diabetes, infections, or injury can lead to neuropathic itch.
- Shingles. The chickenpox virus can reactivate, causing a painful, itchy rash called shingles. Even after the rash heals, some individuals experience lingering nerve pain.
- Spinal cord injuries. Damage to the spinal cord can disrupt nerve signals, causing abnormal sensations like itching.
- Multiple sclerosis. MS can damage nerves in the brain and spinal cord, leading to symptoms like neuropathic itch.
- Stroke. Sometimes after a stroke, areas of the brain responsible for sensation can become damaged, leading to abnormal sensations, such as itching.
Symptoms of Neurological Itch
Neuropathic itch often presents differently than a typical itch associated with skin conditions. Common symptoms include:
- No visible rash or irritation on the skin
- Chronic itching that can last for long periods
- Associated pain, burning, or tingling
- Scratching doesn’t provide relief; in fact, it can worsen it
- Itching may be localized to specific areas of the body, or it can be widespread
- Increase or decrease in skin sensitivity
How Is Neuropathic Itch Treated?
Diagnosing neuropathic itch can be difficult because the symptoms are similar to those of other conditions. Doctors first rule out other skin-related conditions, such as eczema or allergic reactions. If no skin abnormalities are found, and the itching is persistent, you may want to see a neurologist to have your nerves evaluated. Some of the tests that can assess nerve damage include nerve conduction studies, MRI or CT scans, and blood tests.
Treatment Options for Neurological Itch
Unlike other skin conditions, neuropathic itch can be difficult to treat. This is the case because the underlying cause is from the nervous system rather than the skin. However, there are various treatment options available such as medications for nerve pain, topical treatments, antidepressants or anticonvulsants, behavioral therapies, and nerve blocks. Additionally, managing conditions that lead to neuropathic itch, such as diabetes or MS, can help control the symptoms.
