Climber's finger  Climber's finger is one of the most common climbing injuries within the sport of rock climbing. It is an overuse injury that usually manifests in a swollen middle or ring finger due to a damaged flexor tendon pulley, normally the A2 or A4 pulley. It is particularly common after a repeated utilization of small holds. Continued climbing on an injured finger may result in increased downtime in order to recover. Management of tendon injuries in the fingers is to follow the RICE method.
