Trigger finger is a condition that makes it difficult to move your fingers or thumb. It has the capacity to “freeze” them in a flexed position and affect the tendons in your fingers and thumbs. The term “finger-stuck” is derived from the position in which your fingers can become ensnared. In actuality, it looks like you’re trying to move an invisible finger.
If you have a trigger finger, your fingers or thumb might become stuck flexed inward toward your palm. Your affected digits may be difficult or impossible to straighten. In addition, trigger finger can affect any of your fingers; however, it is most frequently observed in the ring finger of affected individuals.
Consequently, how can one ascertain whether they have trigger finger? One of the most common symptoms of trigger finger is a snapping or popping sensation that occurs when the fingers or thumb are moved. Your affected fingers may feel as though they are “catching” or becoming stuck during movement.
In addition, you may experience swelling or a tender lump in the palm of your hand, as well as pain and stiffness when flexing your fingers or thumb in toward your palm. It also entails soreness in the region of your palm that is near the base of your fingers or thumb. This pain is typically worse when you are grasping or gripping something.
Trigger finger symptoms, especially stiffness and fixed positions, typically get worse in the morning. Your stiffness typically improves marginally as you begin to use your fingers and thumb throughout the day.
Consequently, what is the etiology of trigger finger? Trigger finger or trigger thumb is characterized by swelling in or around the tendons of the fingers or thumb. Tendons are tissue connections that serve as the intermediary between muscles and bones, in case you were unaware. The muscles and tendons in your hands work together to flex and straighten the fingers and thumb.
A sheath, which functions as a tissue conduit, encases these tendons. The sheath protects the tendons and ensures that they remain in their correct position. When the tendons in the affected fingers or thumb become irritated and swollen, trigger finger occurs, which prevents them from easily passing through their sheaths.
Additionally, the protrusion of your affected tendon makes it more difficult for the tendon to travel through its sheath without difficulty. Although anyone can get trigger finger, people between the ages of 40 and 60 are more susceptible.
