Injuries that involve tearing or stretching of the ligaments of your fingers is termed a sprain. Sprains in the fingers are most often caused from a fall when you extend your arms to reduce the impact of the fall, or from overuse or repetitive activity of the thumb such as with texting.
Some of the symptoms of finger sprains include:
Finger sprains are diagnosed with the help of a physical examination of the hand to check for any abnormalities by moving your fingers in different positions. Your doctor may also suggest imaging tests such as X-rays to find the exact location of the injury.
Finger sprains can be treated with the help of applying ice packs and immobilizing your finger to allow it to heal. You may also be given pain medications to reduce discomfort. Once your fingers heal, you will be advised to perform strengthening exercises to strengthen your fingers. Surgical treatment is very rare and may be required only in complex cases where the ligament is completely torn.
