Finger and Fingers Locking Up (and More Causes)

The article outlines trigger finger, describing symptoms when fingers “lock up” and what may cause the condition. It notes that risk factors include age, sex, and activities involving strong gripping. Trigger finger occurs when the tendon sheath becomes inflamed, preventing smooth gliding of the tendon. Typical presentation involves the affected digit stuck in a curled or bent position toward the palm, sometimes with a “pop” when straightening. The article differentiates painless, gradual clicking from painful cases that may include discomfort at the base of the finger or thumb, relief at rest, increasing pain over time, pain with bending, and inability to fully straighten. It also lists related risk factors such as rheumatoid arthritis, gout and diabetes, and mentions other conditions to consider in diagnosis, including Dupuytren’s contracture.
