 The location of the reference point for each individual that experiences referred itch is well conserved and specific to each person, in that a certain location will elicit the phenomenon repeatedly for a given person while itches elsewhere may not.However, frequent and repetitive stimulation of the same original itch location can weaken the phenomenon, making the referred itch increasingly more discrete with each repeated trial.There is also no evidence of a relationship between the site of the original stimulus and that of the referred itch.
