About one person in four or five is conscious that scratching an irritation may produce an itch elsewhere. The sensation is well localised, comes and goes quickly, and recurs when scratching is repeated a short while later. Scratch and referred itch are ipsilateral; scratching the site of the referred itch does not cause the original spot to itch. Scatching face, palms, or soles does not produce referred itching. Different people stimulated in the same region do not necessarily feel referred itch in the same place. The mechanism of the phenomenon is unknown, though it may be thalamic.
大约每四五个人中就有一人意识到搔抓一处痒处可能会在其他地方引发瘙痒。这种感觉定位明确，来去迅速，且在短时间后再次搔抓时会复发。搔抓和牵涉性瘙痒是同侧的；搔抓牵涉性瘙痒的部位不会导致原来的部位瘙痒。搔抓面部、手掌或脚底不会产生牵涉性瘙痒。在同一区域受到刺激的不同人不一定会在同一部位感到牵涉性瘙痒。尽管这种现象的机制可能与丘脑有关，但其尚不清楚。
