Frequent texting can trigger tendonitis Tendonitis is a modern disease in which the most delicate parts are the 19 small muscles in the hand. The coordinated movement of these muscles helps humans perform many fine movements. However, it is the excessive sending and receiving of text messages and mechanical repetition of the same action that leads to strain on the thumb tendon, which obstructs the movement of the tendon sheath and prevents it from moving, thus triggering tendovaginitis. Tenosynovitis is one of the most common diseases caused by the rapid development of computer science and technology in modern society, and occurs in people who use computers for a long time or need to maintain the same posture for a long time. Tenosynovitis is caused by excessive strain on the joint, mostly in the metacarpal joint and the root of the thumb, but most commonly in the radial tuberosity and the head of the first metacarpal. The tendon sheath becomes thickened due to fibrous degeneration caused by strain injury, resulting in narrowing of the sheath and restriction of tendon movement within the sheath, hence the name tendovaginitis. The strain on the joint tendon results in edema, pain, and difficulty moving, which is often referred to as “trigger finger” or “popping finger”, or stenosing tendovaginitis. If tendonitis is not treated properly, it may cause lifelong mobility problems. The solution to tendonitis is to reduce the number of text messages, do not do continuous flexion and extension of the fingers, pay attention to rest, and secondly, you can do massage, heat or physical therapy. Then buy some ointment specifically for the treatment of tendinitis. The most important thing for tendonitis recovery is the need for more exercise, more rest, if the drug can not reduce inflammation, then you can consider surgery. If the thumb is held tightly within the other four fingers and the wrist is flexed to the medial (ulnar) side of the wrist, severe pain occurs at the radial styloid process. In the acute phase, there may be localized swelling. When the swollen tendon passes through the narrow tendon sheath as a “tunnel”, the thumb will ring when it is flexed, which is also known as “ringing finger”. (2) Tenosynovitis of the flexor tendon occurs mostly in the thumb and middle finger. The affected finger flexion and extension dysfunction, especially obvious when waking up in the morning, can be reduced or disappear after activity. The pain sometimes radiates to the wrist. There may be pressure pain in the metacarpophalangeal joint when flexed, and sometimes thickened tendon sheaths and pea-sized nodules may be palpable. When bending the affected finger, it suddenly stays in the semi-bending position, the finger can neither be straightened nor flexed, like being suddenly “stuck”, with unbearable pain. “the name.
