Trigger finger, also known as stenosing tenosynovitis, is a disorder characterized by catching or locking of the involved finger in full or near full flexion, typically with force. [2] There may be tenderness in the palm of the hand near the last skin crease (distal palmar crease ). [ 3 ]
Symptoms are pain and tenderness at the radial side of the wrist, fullness or thickening over the thumb side of the wrist, painful radial abduction of the thumb, and difficulty gripping with the affected side of the hand. [2] Pain is made worse by movement of the thumb and wrist, and may radiate to the thumb or the forearm. [2]

Nerve block or regional nerve blockade is any deliberate interruption of signals traveling along a nerve, often for the purpose of pain relief. Local anesthetic nerve block (sometimes referred to as simply "nerve block") is a short-term block, usually lasting hours or days, involving the injection of an anesthetic, a corticosteroid, and other agents onto or near a nerve.
The joint closest to the tip is the distal interphalangeal (DIP) joint. The next joint, moving closer to the hand, is the proximal interphalangeal (PIP) joint. The injured finger may be examined to determine where the pain is worst. [3] If the finger is sprained or dislocated, pain will be worse at the joint rather than the bone. [3]
