Fingers can lock up due to a condition known as trigger finger, which occurs when the tendon that controls finger movement becomes inflamed or irritated. This inflammation can cause the tendon to catch on the surrounding sheath, leading to a locking or catching sensation. Other factors, such as repetitive hand movements, certain medical conditions like Diabetes or rheumatoid Arthritis, and age-related changes, can also contribute to this issue. In some cases, it may resolve on its own, while more severe cases might require medical intervention.
