Trigger finger is a problem that impacts one or more of the hand's ligaments. See your general practitioner if you think you might have trigger finger. Symptoms of trigger finger can consist of: pain at the base of the affected finger or thumb when you relocate or continue it; rigidity or clicking when you move the affected finger or thumb, especially first point in the morning. A number of variables may increase the possibility of trigger finger developing. Another hand-related problem called Dupuytren's contracture can also increase your risk of developing trigger finger. In Dupuytren's contracture, the connective tissue in the palm of the hand thickens, creating one or more fingers to flex into the palm of the hand. When you tighten up a muscle, it pulls on the tendon, and this causes the bone to move. The ligaments that move your finger slide via a tendon sheath as you flex your finger. If the passage swells and lessens, or the tendon has a bump on it, the tendon can not glide efficiently via the tunnel. Trigger finger usually does not need x-rays or laboratory tests. You can have greater than one trigger finger and it can develop in both hands. If a tendon or the passage a ligament goes through becomes swollen and inflamed, the ligament obtains inflamed and can "catch" in the ligament sheath. You may have pain in your hand even when it's still if the problem obtains worse. You might additionally get a lump in your palm and your finger may get embeded a curved setting and then suddenly pop right.
