Trigger finger is a condition that affects the hand and fingers. It occurs when one of your fingers or thumb gets caught in a bent position, causing pain, swelling and difficulty in straightening it out. The cause of trigger finger is often not clear but it can be associated with certain medical conditions such as rheumatoid arthritis, diabetes or thyroid disorders. In some cases, it may also result from repetitive stress on the hand or fingers.
The symptoms of trigger finger include pain, tenderness and swelling at the base of the affected finger or thumb. You may also experience a popping or clicking sensation when you try to straighten your finger. As the condition progresses, it may become difficult to move your finger and you may feel like it is stuck in a bent position.
Treatment for trigger finger typically involves non-surgical options such as resting the affected hand, applying ice or taking anti-inflammatory medications. In some cases, a corticosteroid injection may be recommended to reduce inflammation and alleviate pain. If these methods are not effective, surgery may be necessary to release the tendon and restore normal movement in your finger.
