A jammed finger can be a small fracture, dislocation or a sprain to one of the joints, says Mayo Clinic. The injury can be painful and the joint can swell.
To treat a jammed finger, Mayo suggests:
- Ice the finger with a cold pack for up to 15 minutes.
- Elevate the hand to reduce swelling.
- Tape the injured finger to an adjacent finger.
Seek prompt medical care if the finger appears deformed, if the injured person develops a fever or if the finger becomes numb.
