What is Trigger Finger?
Trigger finger, also known as stenosing tenosynovitis, which affects one or more flexor tendons of the hand and makes it difficult to bend the fingers or thumb. There are pulleys on each finger that allow finger tendons to pass through. Therefore the fingers can move freely in full range of extension and flexion. Trigger finger is thought to be the inflammation and thickening of the finger pulleys and the progressive inflammation of the tendon, and the tendon sheath may cause pain at the fingers and clicking during finger movement. The prevalence rate is around 2-3% in normal population, but it increased to 10% in diabetic population. Repeated forceful contraction of finger flexion, for example when carrying heavy shopping bags, prolonged writing or typing, rock climbing etc., is associated with the development of trigger finger.
Common early symptoms includes:
- Persistent soreness at the base of your thumb or another finger
- A bump or lump near the palm at the base of the affected finger
- Tenderness surrounding the base of the finger
- A clicking or snapping sound during movement
- Stiffness in the finger
