Trigger finger, also known as stenosing tenosynovitis, occurs when one of your fingers or your thumb gets stuck in a bent position. It is difficult to straighten it without pulling on it by the other hand. The trigger finger can be severe; may become locked in a bent position, and can often be painful. It is caused by a narrowing of the sheath that surrounds the tendon in the affected finger.
Those who require repetitive gripping actions are more susceptible and it is also more common in women and in people who have diabetes. Most cases occur for no apparent reason in healthy people. Sometimes, the trigger finger is more common in people with Rheumatoid arthritis, Carpal tunnel syndrome, Amyloidosis and in people on dialysis.
Signs and symptoms of Trigger finger include:
• Popping or clicking sensation as you move the finger
• Stiffness of the finger, particularly in the morning
• Finger locking in a bent position, which you're unable to straighten
• A bump or tenderness at the base of the affected finger
If you're finger joint is hot or inflamed, see your doctor immediately for a physical evaluation of your hand!
