Main Causes Of Trigger Finger
Trigger finger most often develops due to inflammation or irritation of the flexor tendons in the hand, which can be caused by repetitive gripping or overuse. Certain health conditions, such as diabetes and rheumatoid arthritis, can also increase the risk of developing this condition. In some cases, trigger finger may result from direct injury to the palm or base of the finger. Prolonged inflammation leads to thickening of the tendon sheath, making finger movement difficult and sometimes painful.
