Symptoms of trigger finger are mild in the beginning and gradually progress to severe form. Commonly affected areas include thumb, middle finger and ring finger.

Symptoms noted include:

• Finger stiffness, especially in the morning
• A popping or clicking sensation when moving the fingers
• Tenderness or bump in the palm, at the base of the affected finger
• Locking of the finger in a bent position and straightening suddenly

Trigger finger results from irritation and inflammation of the tendon sheath in the fingers, which leads to narrowing of the space within the sheath. The irritation and inflammation may be due to:

• Repetitive gripping or grasping action
• Keeping the fingers bent for a long duration
• Certain medical conditions: e. g. medication for diabetes or rheumatoid arthritis
• Gender: Women are more at risk of developing trigger finger

Prevention

• Avoid bending your fingers for long durations
• Learn simple exercises to relax your fingers between work
• Wear protective gloves to avoid injuring your fingers
• Consult your doctor immediately in case you notice any changes in your fingers

Locking of the affected finger in bent position and the inability to straighten the finger.
