fiddler's neck

Pressure from the chinrest against the player's skin can result in a common irritation known as "fiddler's neck" or "plague".

They are often seen in violin, viola, and cello players, along with fiddler's neck and other dermatologic conditions peculiar to string musicians.

Cutaneous disorders in musicians include frictional injury ("fiddler's neck"), hyperhidrosis, acne mechanica and vascular compromise.
