 Referred itch is commonly observed in completely healthy individuals and can often go unnoticed depending upon the particular person’s self-awareness of their itches and the causes of those itches.The ephemeral nature of referred itch and its restriction to a very small area on one’s body (the itch is precisely located, it does not induce widespread itching) make it difficult to document or even notice.The majority of the cases of referred itch studied by experimenters occur in healthy individuals.
