With the popularity of computers, more and more people are working with computers, but working in the same posture repeatedly for a long period of time can cause tendonitis, which can bring pain to people’s work and life. Tendonitis is usually caused by repetitive or continuous exertion, resulting in friction between the tendon and tendon sheath, strain, and increased pressure, leading to aseptic inflammation. What are the most prevalent groups of people with tendonitis? 1. Middle-aged and older women. These people are often engaged in tedious daily household activities, the fingers and wrists must be repeatedly strained, so they are prone to tendinitis. 2, some occupational groups that require long-term repetitive strain on the joints. Typists, instrumentalists, cargo handlers or those who need to operate computers for long periods of time are susceptible to this disease because of the repeated use of wrists and fingers, which can easily lead to strain and trauma. This disease is mostly seen in computer operators, so it is called “mouse hand” or “keyboard hand”. What are the signs of tenosynovitis in the wrist? Pain occurs when the wrist is strained or deflected toward the little finger, sometimes very suddenly and violently. Swelling and heat may occur at the base of the thumb of the wrist, and a bulge may be felt and painful when pressed. What should I do if I have tenosynovitis of the wrist? The purpose of tendovaginitis treatment is to relieve pain, reduce inflammation, and restore limb function. By taking oral non-steroidal anti-inflammatory drugs, Chinese herbal medicine external washing, external application, local application of antipyretic and analgesic cream, local closure, etc. can relieve pain symptoms and reduce inflammation, but most importantly, the wrist should get sufficient rest. Changing poor living and working posture will help to reduce the bad stress on the wrist and help the inflammation to subside. In the short term it is best to do less or no housework and carry children, or at least to exert less force on the wrist on the side that hurts. Many people can get better with conservative treatment, so don’t worry too much. If you are still unable to rest your hand and wrist, sometimes the painful symptoms can last for a long time, affecting the ability to exert your hand and perform work, and in severe cases, surgery is required for treatment.
