There are 2 main reasons why tendonitis occurs: 1. The tendon sheath is wrapped around the human tendon, and her role is to reduce friction, increase lubrication and form the fulcrum of the tendon during stretching movements. The tightness of the tendon sheath is not very consistent for each person, and the more tense, the easier it is to develop tendonitis. 2, almost all tendinitis patients have a history of repeated and repetitive stretching movements of the tendon, excessive repetitive activities can lead to tendon sheath injury, when the injury exceeds the self-repair ability of the tendon sheath will appear tendinitis, first edema, inflammation, etc.. Eventually hyperplasia, stenosis, and entrapment occur. Prevention: The 2 most critical things are: 1. Repeated movements that lead to tenosynovitis need to be stopped, avoided or reduced, otherwise it will be difficult to cure with any medication. 2, release the jam: if it has been recurrent for months, medication, rest can not be relieved, pain, movement is limited, it means that the tendon sheath jam is serious, you should surgery to release. This procedure is effective and has immediate results. After the surgery, the involved joint was relaxed and the movement was basically free. Postoperatively, rehabilitation exercises are gradually performed. It is worth noting that although a minimally invasive incision is used, the wound is basically no more than 1 cm and the compression is resolved immediately. However, this is a relatively delicate surgery. It is easy to damage the nerves and blood vessels on both sides and the tendons underneath if inexperienced. In addition, not all tendinopathies require surgery. Most people have probably experienced tendonitis in a joint due to repetitive movements. Typically, tenosynovitis occurs when you count money with your hand every day and one of your fingers is not relaxed enough during movement, such as bank workers who are prone to tenosynovitis of the dorsal aspect of the index finger and the radial aspect of the wrist. People who knit sweaters are prone to tendinitis of the flexor tendon of the thumb. When you repeatedly use a certain finger, resulting in tendinitis symptoms, first of all, rest, and then apply drugs to relieve pain and inflammation (important creams from regular manufacturers, or Furtalin ointment, etc.), topical topical drugs are the main ones, most of which can be relieved. In short, tendonitis is a minor problem, but the restricted movement and pain can really kill you. But do not worry, if, reasonable treatment, if necessary to take professional surgery, he is just a minor problem.
