Stenosing tenosynovitis is more common in middle-aged women's thumb and middle finger, and the fingers will bend automatically. When you stretch, at a certain angle, you suddenly can't stretch. To exert force, stretch like a spring.
Stenosing tenosynovitis is mostly caused by excessive use of hands, so the most important thing is not to over-stimulate fingers, keep quiet, apply hot and wet compress and steam bath. In addition, corticosteroid preparations are also effective. When the tendon sheath becomes thicker and cannot be cured by the above methods, the thickened tendon sheath can be partially removed to restore the tendon function to normal.
