Trigger Finger: Causes, Treatments, and Interventional Pain Management
Trigger finger, medically known as stenosing tenosynovitis, is a condition characterized by a painful locking or catching sensation in the fingers or thumb. It occurs when the tendons that control finger movement become inflamed and develop nodules, restricting their ability to glide smoothly through the tendon sheath. This condition can significantly impact hand functionality and quality of life.
