The term jammed finger refers to finger joint pain and swelling from an impact injury. It's the most common injury in sports. This injury tends to be very painful, and immediate treatment will usually help healing the joint faster. Most jammed fingers heal relatively quickly, if no fracture occurs. If there is a fracture, however, the healing process will take longer; anywhere from one or two weeks to several months, and the methods of healing will become more in depth. Toes can become jammed as well, but not as often as fingers.
