Local pain of radial styloid process

Radial styloid stenosing tenosynovitis mainly manifests as localized pain in the radial styloid process. The onset of the disease is slow, gradually worsening, pain at the bone process (radial styloid process) on the thumb side of the wrist and around the thumb, hindered thumb movement, tenderness and friction at the radial styloid process, and sometimes at the radial styloid process Swelling pea-sized nodules slightly. If you hold your thumb firmly inside the other four fingers and flex your wrist towards the medial side of the wrist (ulnar side), severe pain will occur at the styloid process of the radius. In the acute phase, swelling may occur locally. When the swollen tendon passes through the narrow tunnel of the tendon sheath, the thumb will make a sound when it flexes flexibly, which is also known as "flicking fingers".
