A sprain is an injury to a joint that causes a stretch or tear in a ligament. Ligaments are strong bands of tissue that connect one bone to another.
A sprain usually occurs when there is an accident. For example, a ball may hit the tip of your finger or you may fall forcefully onto your finger.
You have pain, swelling, and tenderness in your finger.
Your health care provider will examine your finger. You may have an x-ray to be sure you have not broken any bones in your finger.
Treatment may include:
Your health care provider will recommend that your sprained finger be splinted or "buddy taped" (taped to the finger next to it) for 1 to 4 weeks after your injury.
The goal of rehabilitation is to return you to your sport or activity as soon as is safely possible. If you return too soon you may worsen your injury, which could lead to permanent damage. Everyone recovers from injury at a different rate. Return to your activity will be determined by how soon your finger recovers, not by how many days or weeks it has been since your injury occurred. In general, the longer you have symptoms before you start treatment, the longer it will take to get better.
Your finger may remain swollen with decreased range of motion and strength for many weeks. It is important to continue your rehabilitation exercises during this time and even after you return to your sport. In many cases, you will be able to return to your activities as long as you are wearing your splint or have your finger taped.
Finger sprains are usually the result of injuries that are not preventable.
