Understanding trigger finger
Trigger finger, medically known as stenosing tenosynovitis or flexor tenosynovitis, is a common hand condition that affects the tendons in the fingers or thumb. This condition occurs when the tendons, which normally glide smoothly through the tendon sheath when the finger is bent or straightened, become inflamed or thickened. This can lead to difficulties in finger movement.

The exact cause of trigger finger is not always clear, but several factors can contribute to its development:
Repetitive Motion: Frequent and repetitive hand and finger movements, such as gripping tools or typing, can strain the tendons and lead to a trigger finger.
Underlying Medical Conditions: Certain medical conditions, such as diabetes and rheumatoid arthritis, are associated with an increased risk of trigger finger.
Age and Gender: It is more common in women and individuals aged 40 and older.
