Allodynia

Allodynia describes a situation where harmless stimuli — such as a light touch, gentle pressure, or even clothing brushing against the skin — are perceived as painful.

This is a hallmark of neuropathic pain, where the nervous system processes signals abnormally. Allodynia can significantly affect quality of life, making everyday activities uncomfortable or distressing. Recognizing allodynia is important for tailoring treatment, since standard painkillers often have limited effect and other strategies, like anticonvulsants, antidepressants, or neuromodulation, may be more effective.
