Trigger Finger
Mild
Trigger finger is a condition in which a finger catches, locks, or becomes difficult to straighten after being bent. It occurs when movement of a tendon through its surrounding sheath becomes restricted, often causing pain, stiffness, or a clicking sensation. Symptoms may be more noticeable after periods of hand use and can interfere with normal finger movement.

When to Seek Medical Attention
Trigger finger is usually not an emergency. Seek medical assessment when finger catching, locking, pain, or stiffness persists or interferes with normal hand function. Prompt evaluation is appropriate if the finger becomes completely locked, develops significant swelling or redness, or symptoms follow a substantial injury.

Overview
Trigger finger is a condition in which a finger catches, locks, or becomes difficult to straighten after being bent. It occurs when movement of a tendon through its surrounding sheath becomes restricted, often causing pain, stiffness, or a clicking sensation. Symptoms may be more noticeable after periods of hand use and can interfere with normal finger movement.
Symptoms 2
Back Pain
Frequent Hunger
Causes 1
Trigger finger commonly develops when a tendon and its surrounding sheath become irritated or swollen, making smooth tendon movement difficult. Repetitive hand use, forceful gripping, and activities that repeatedly stress the fingers may contribute. The resulting inflammation can cause the tendon to catch as the finger bends or straightens, producing clicking, stiffness, or locking.
Insulin Resistance
Risk Factors
Risk of trigger finger may increase with repetitive gripping, forceful hand use, or activities that place repeated stress on the fingers and palm. Diabetes is also associated with a higher likelihood of developing the condition. Other factors that may contribute include repeated hand strain and occupations or activities requiring frequent gripping or prolonged use of the hands.
Diagnosis
Diagnosis is based on a patient's medical history,
symptoms, physical examination and, when necessary,
laboratory or imaging investigations.
Trigger finger is usually diagnosed from the person’s symptoms and a physical examination of the affected hand. A healthcare professional may observe the finger while it bends and straightens and may feel for tenderness or thickening near the base of the finger. Imaging is not usually required, but additional testing may be considered when another condition is suspected.
Prevention
Key Prevention Tips
Trigger finger may not always be preventable, but reducing repeated gripping and forceful hand movements may lower irritation of the tendon
Taking breaks during repetitive activities, using appropriate tools and hand positions, and avoiding prolonged pressure on the palm can help
Conditions associated with trigger finger, such as diabetes, should be managed with appropriate medical care
Persistent locking or painful finger movement should be evaluated
Prevention Guidance
Trigger finger may not always be preventable, but reducing repeated gripping and forceful hand movements may lower irritation of the tendon. Taking breaks during repetitive activities, using appropriate tools and hand positions, and avoiding prolonged pressure on the palm can help. Conditions associated with trigger finger, such as diabetes, should be managed with appropriate medical care. Persistent locking or painful finger movement should be evaluated.
Reminder: Prevention recommendations should be tailored to your personal health status and risk factors.
