中枢や末梢の神経障害で、外部からの刺激がないのに自発的に経験する異常な感覚を指す。
Any abnormal sensation described as unpleasant by the patient.(疼痛#痛みと異常知覚の命名法)
Dysesthesias are distorted sensations in response to a stimulus and may last longer than the stimulus itself. For example, a person may perceive a light touch or pinprick as a burning or tingling sensation that is irritating or unpleasant.

( Bates Guide to Physical Examination p.550より抜粋)

Mainly spontaneous abnormal sensation that is not unpleasant; usually described as "pins and needles".(疼痛#痛みと異常知覚の命名法)
There may be peculiar sensations without an obvious stimulus, called paresthesias. These occur commonly when an arm or leg “goes to sleep” following compression of a nerve, and may be described as tingling, prickling, or feelings of warmth, coldness, or pressure.
