Finger sprains are often splinted or buddy-taped (taped to an adjacent finger) for a short period of time. So long as there was no fracture or dislocation, most finger sprains should be allowed to move within about a week. Splinting the sprained finger during sports can help protect the injury, but unnecessarily splinting the finger cause cause it to stiffen up. You should discuss with your doctor when to begin finger movements.
Other treatments for a sprained finger include:
- Ice the injured finger
- Elevate if there is swelling
- Take an anti-inflammatory medication
- Gently move the finger to prevent stiffening
