Trigger Finger
With trigger finger, the flexor tendon that controls finger and thumb movement gets stuck. This restricts movement of the finger or thumb, causing a tender lump in the palm, swelling, a popping or pain as the finger straightens, stiffness, or the finger/thumb to be stuck in a bent position. Certain repetitive hand uses and some illnesses like diabetes or rheumatoid arthritis can cause trigger finger, and it is most often seen in women.
