Understanding Trigger Finger: Whatâs Really Going On
Trigger finger â also known as stenosing tenosynovitis â is a condition where a finger catches, clicks, or temporarily locks when you try to bend or straighten it. Although it feels like a joint problem, the issue actually comes from the flexor tendon and the small sheath it glides through.
When the tendon becomes irritated or thickened, it no longer glides smoothly through its sheath - almost like a rope getting caught in a pulley. This creates friction, swelling, and the classic âcatchingâ sensation patients describe. Over time, the tendon may momentarily lock in a bent position before suddenly releasing, similar to a trigger snapping back.
Common Symptoms
- Pain or tenderness at the base of the affected finger or thumb
- A clicking or popping sensation with movement
- Stiffness, especially first thing in the morning
- Finger locking in a bent position that requires assistance to straighten
Why It Happens
Trigger finger often develops from repetitive gripping, prolonged tool use, inflammation in the hand or forearm, or underlying conditions that increase tendon irritation. Even everyday activities â typing, lifting, or holding a phone â can contribute when the tissues are already irritated.
How Chiropractic Care Can Help
Chiropractic treatment focuses on restoring proper mechanics in the hand, wrist, and forearm, which reduces strain on the flexor tendons. By improving joint alignment, decreasing local inflammation, and addressing muscle tension patterns, we help the tendon glide more freely and reduce the catching sensation.
Early care is important. When addressed promptly, most patients experience significant improvement in comfort and function without needing more invasive interventions.
If your finger has been catching, clicking, or locking, itâs worth having it evaluated before symptoms progress.
