An abnormal or distorted sense of touch or feeling, where normal sensations feel uncomfortable or different than they should.
From Greek dys- (bad/difficult) + aesthesia (sensation/feeling), combining form used in medicine since the 1800s to describe altered sensory perception.
People with dysaesthesia might feel like their skin is burning when it's just lightly touched—it's not pain exactly, but the sensation gets scrambled by the nervous system, which is why neurologists use this term to distinguish it from regular pain.
