How does trigger finger occurs?
Overuse and abuse of a certain limb, muscle, or other body part is the main cause of trigger finger. The tendons that allow the bones of our body to move can only do so because of the passageways that are provided through ligaments. Normally, the tendons can move through the ligaments smoothly and effectively, allowing motion to occur naturally and without pain. However, the tendon sheath can become inflamed, causing it to move improperly through the finger. When this occurs, a case of trigger finger is the result. A nodule may form due to the aggravation, and it will grow in size until the problem is treated. The afflicted individual will be unable to properly move their finger if the nodule grows to be big enough. The causes of trigger finger can vary. It’s often experienced due to many tiny micro-tears in the ligament as a result of trauma.
