Allodynia refers to pain caused by what would normally be non-painful stimulation, for example brushing the skin. Temperature change, light touching, and clothing can trigger the pain response resulting in a burning sensation often occurring after an injury to a site.
Presentation[edit | edit source]
There are three types of allodynia. Tactile, where pain is caused by touches such as clothing touching the skin or someone lightly touching the arm; Mechanical, caused by movement across the skin when drying with a towel or sheets brushing against the skin; and Thermal, which is caused by heat or cold that is not extreme enough to cause damage to skin tissues.
Allodynia in ME/CFS and Fibromyalgia[edit | edit source]
Allodynia is not a diagnostic symptom of ME or CFS, and is not even referred to in the International Consensus Criteria Primer for ME although over forms of pain are.

chronic fatigue syndrome (CFS) - A fatigue-based illness. The term CFS was invented invented by the U.S. Centers for Disease Control as an replacement for myalgic encephalomyelitis (ME). Some view CFS as a neurological disease, others use the term for any unexplained long-term fatigue. Sometimes used as a the term as a synonym of myalgic encephalomyelitis, despite the different diagnostic criteria.
