Trigger Finger Causes
Often trigger finger is linked to either repetitive or forceful motion. Like tendonitis and carpal tunnel syndrome, people who frequently use their hands for their way of life are the ones who are often affected. It is the motion of the work that can cause trigger finger, and it is the work that is limited by the condition. Musicians, construction workers, typists; anyone who uses their fingers and thumbs on a regular and somewhat intense basis can have problems.
What causes trigger finger is inflammation of the tendon, which can be caused by the repetitive or intense motion. The tendon becomes increasingly irritated and swollen. It thickens and nodules can form, making it more and more difficult to pass through its protective sheath with ease with each flex and extend movement. Eventually, the tendon gets stuck for a moment when you try to move your finger or thumb, and then pops through the sheath. When it does pop through, the appendage can shoot straight out suddenly.
Cases of trigger finger occur more frequently in women than men. Furthermore, people within the 40 to 60 age group are most affected. While some sort of work, strain, or even an injury to the tendons is often behind this condition, it is also possible for other medical conditions to cause trigger finger. People with rheumatoid arthritis, diabetes, and gout can have problems due to changes in tissue.
