Common Causes of Trigger Finger
Several factors are known to contribute to the development of the trigger finger. The tendons in our fingers are protected by a sheath that helps them move smoothly. When these sheaths are inflamed, it can cause the tendon to become stuck, leading to a trigger finger.
Other factors may include:
Repetitive Strain Injury (RSI)
Repetitive strain injury (RSI) is a common cause of trigger finger. This occurs when the tendons in the fingers are overused and become inflamed.
Rheumatoid Arthritis
Rheumatoid arthritis, or RA, is an autoimmune disorder that can cause inflammation in the joints and tendons, including fingers.
Gout
Gout is an arthritis that causes pain and swelling in the joints, including those in the fingers.
Diabetes
Diabetes directly leads to a higher risk of developing trigger fingers due to the damaging effects of high blood sugar on tendons and sheaths.
