A jammed finger is typically a sprain to the joint or knuckle, of the finger. There may also be a small fracture or dislocation of the joint. The injury can be extremely painful, and the joint usually becomes swollen. A jammed finger is a common sports injury. For example, your fingertip receives the full impact of a hard hit baseball, basketball rebound or volleyball spike.
This type of injury may also result for other reasons. You reach out your arm to break a fall, and your finger jabs into the ground. The result is often a jammed finger. This type of injury usually heals quickly if there is no fracture, although the pain may linger for months when direct pressure is applied to the finger.
To treat a jammed finger:
Ice the finger with a cold pack for 15 minutes. Placing your finger in ice water works, too.
Elevate your hand to reduce swelling.
To protect the finger during use:
Buddy tape the injured finer to an adjacent finger use a self-adhesive wrap to tape above and below the finer joint -- for example, index finger to middle finger or ring finger to small finger.
Seek medical care if:
Your finger appears deformed.
You cannot straighten your finger.
