Allodynia refers to central pain stimulation usually following a non-painful stimulus. There are many types of allodynia, including mechanical (static or dynamic; pain in response to being touched), thermal allodynia (pain from ordinarily mild temperatures in contact with the affected area), and movement allodynia (pain that is triggered by normal movement of muscles or joints).

Allodynia Symptom: Pain

Pain is the primary symptom of allodynia, caused by stimuli that don’t usually cause pain. A person may find cold or hot temperatures painful. They might also experience soreness from gentle pressure or touch on the skin. Some might even feel pain in response to a brushing sensation or another movement along the hair or skin.

Allodynia Cause: Fibromyalgia

Fibromyalgia causes people to feel joint and muscle pain throughout the body, unrelated to an injury or a condition. It is linked to the way your brain processes pain signals from the body. Certain viruses, trauma, or stress might also trigger fibromyalgia.

Cause: Migraine Headaches

A migraine is a headache that causes intense pain. Chemical activity and changes in the nerve signals in your brain trigger this type of problem. These headaches can also make your nerves so sensitive even the slightest touch can hurt. Not everyone who experiences migraines also experiences allodynia.

Cause: Postherpetic Neuralgia

Postherpetic neuralgia is the most common complication of shingles, a disease caused by the varicella-zoster virus, which also causes chickenpox. Due to shingles or chickenpox, your nerves can become damaged and you can develop postherpetic neuralgia. A potential symptom of this is heightened sensitivity to touch.

Cause: Peripheral Neuropathy

Peripheral neuropathy occurs when the nerves that connect the body to the spinal cord and brain become destroyed or damaged. The condition often causes weakness, pain, and numbness, usually in the hands and feet, but it can affect other areas of the body, as well. People with peripheral neuropathy generally describe the pain as burning, tingling, or stabbing.

Cause: Diabetes

Over time, diabetes can cause damage to nerves, increasing the chance of developing allodynia. Nerve growth factor, or NGF, is essential to the nervous system, and some experts have suggested diabetes can lower your NGF levels, resulting in diabetic nerve damage.

Treatment: The Underlying Cause

If your doctor is aware of from where your allodynia stems, he or she may be able to treat the underlying cause. For example, if migraines are to blame, your medical provider may prescribe a medication or suggest an exercise that could relieve or prevent them.

Treatment: Lifestyle Changes

Light exercise, a more healthful diet, and getting enough sleep may help alleviate the pain and discomfort of allodynia. Quitting smoking may also help. Although these changes will not cure allodynia, they can help enhance overall health and allow individuals cope.
