Allodynia is a neuropathic pain (involving the nervous system) where an individual is severely sensitive to touch, making the most harmless activities immensely painful, such as combing your hair or wearing a shirt of a particular material–like cotton, for example.
Types of Allodynia
Depending on the type of allodynia, certain kinds of sensations will trigger neuropathic pain that is typically sharp, stinging, or burning.
The three types of allodynia are:
- Dynamic – Pain caused by an object rubbing across the individual’s skin.
- Static – Pain caused by gentle touching or pressure.
- Thermal – Pain caused by changes in temperature.
What Causes Allodynia?
There are a few things ranging from conditions to medications that can cause allodynia, including:
- Diabetes-related neuropathy
- Trigeminal Neuralgia
- Complex Regional Pain Syndrome
- Amplified Musculoskeletal Pain Syndrome
- Multiple Sclerosis
- Nutritional Deficiencies
- Trauma/Nerve Damage
How is Allodynia Diagnosed?
Your medical professional will ask you about your subjective pain experience – what pain you’re feeling, the intensity of that pain, and how that pain is triggered. They will gather your medical history and the information for any medications you may be taking that could be relevant to what’s causing your pain.
They will then do tests for the likes of diabetes, neurological disorders, and other conditions to identify what underlying conditions may be causing your allodynia, including
- Blood tests
- Urine tests
- MRI scan
- CT scan
- Electromyogram (EMG)
- Nerve Conduction Studies (NCS)
- Quantitative Sensory Testing (QST)
