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.
Symptoms of a finger sprain include pain, swelling, and tenderness in your finger.
Your healthcare provider will examine your finger. You may have an X-ray to be sure you have not broken any bones in your finger.
To treat this condition:
Your healthcare 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.
Your finger may be swollen and have decreased range of motion and strength for many weeks. In some cases, this may be permanent. It is important to continue your rehabilitation exercises.
Everyone recovers from an injury at a different rate. Return to your activities depends on how soon your finger recovers, not by how many days or weeks it has been since your injury happened. In general, the longer you have symptoms before you start treatment, the longer it will take to get better. The goal of rehabilitation is to return to your normal activities as soon as is safely possible. If you return too soon you may worsen your injury.
In many cases, you will be able to return to your activities as long as you wear your splint or have your finger taped.
Finger sprains are usually the result of injuries that are not preventable.
