Understanding Trigger Finger: When Should You Be Concerned?

Trigger finger occurs when the tendons that help flex your finger become irritated, inflamed, and stenotic. This causes the finger to catch or lock in a flexed position, which can be painful. While this condition is often localized due to overuse or injury, in some cases, it may be related to systemic conditions.

What Causes Trigger Finger?

In most cases, trigger finger results from overuse or injury, and treatment can be localized through hand therapy, steroid injections, or, in severe cases, surgical release. However, inflammation from systemic conditions, such as inflammatory arthritis, may also cause trigger finger. In conditions like rheumatoid arthritis or psoriatic arthritis, inflammation in the joints and tendons may restrict motion and lead to trigger finger.

Red Flags to Watch For

Some signs that your trigger finger may be related to a larger condition include swelling in multiple joints, tenderness, warmth, or if multiple fingers develop trigger finger suddenly. Conditions like diabetes can also cause trigger finger due to fibrosis and thickening of the tendons.

Seek Specialist Evaluation

Early diagnosis is essential, especially when autoimmune or systemic conditions may be involved. A rheumatologist can perform diagnostic evaluations, such as musculoskeletal ultrasound, to detect inflammation early. Treating the root cause, rather than just the trigger finger, is key to preventing long-term damage.

Conclusion

If you suspect your trigger finger is related to a systemic issue, seek evaluation. Addressing the bigger problem may help resolve the trigger finger and improve your overall health.
