Unexpected Pain: Causes and Treatment of Allodynia

3. Thermal allodynia

Temperature changes on the skin, even slight ones, can cause thermal allodynia. A few drops of cool water, placed gently on the skin, can result in a painful sensation. A warm breeze or light rain can also produce pain, as can air from a heating and cooling vent. This can be frustrating because attempts to warm or cool the skin to relieve pain can cause additional discomfort. At first, this variation of the condition may be confused with air conditioning-induced muscle spasms.
