A jammed finger is a common injury that can cause pain, swelling, and difficulty moving the finger.
A jammed finger is most commonly caused by an injury to the joint in the middle of the finger, where it bends in half. This joint is called the proximal interphalangeal joint (PIP).
Small ligaments called the collateral ligaments support the PIP joint. A jammed finger may occur when then these ligaments are overstretched or strained.
