What causes trigger finger?
For fingers to bend and straighten properly, tendons must move freely within their protective sheaths. When the tendon or sheath has problems, the tendon can bunch up and form a nodule. This nodule gets caught when straightening the finger, causing a painful clicking sensation.
The exact cause remains unknown, though the condition is more common in women over 40 and in those with arthritis, diabetes, or Dupuytren’s contracture.
Non-surgical treatment for trigger finger
While trigger finger sometimes resolves on its own, treatment should be prioritized to prevent permanent finger bending. Several non-surgical approaches focus on reducing swelling and irritation:
- Rest the affected finger by modifying activities to avoid overuse
- Perform finger exercises recommended by a hand specialist or physical therapist
- Wear a splint to straighten the joint and allow tendon healing
- Take pain medication such as over-the-counter NSAIDs
- Receive steroid injections for stronger pain and inflammation relief when standard medications prove insufficient
While these methods can successfully treat trigger finger, results vary by individual. A hand specialist can help determine the most effective approach for your specific situation.
