Many people know that improper badminton and tennis sports can easily cause tennis elbow, but tennis elbow is not the “patent” of athletes. Tennis elbow can also be common among cooks, housewives, rural women and painters who often work manually. Tennis elbow is also known medically as “humeral epicondylitis”, which was named after the majority of tennis player injuries in the early years. The contraction and tension in gripping things (such as tennis rackets, badminton rackets, oil brushes, kitchen knives, etc.) can cause degeneration, degeneration and tearing of the tendons at the proximal end of these muscles if the posture is not correct and too much use is made of these muscles, thus causing tennis elbow to occur. Middle-aged women around 40 years old are the most common patients in the tennis elbow clinic. Most of them suffer from elbow strain due to their own work, or due to a badminton game. The tendons of many muscles are attached to the elbow, which is a fixed pillar of forearm muscle activity. When the wrist is overexerted, or the time of exertion is too long or too violent, especially when housewives scrub clothes too much, buy and carry baskets, cut vegetables, mop the floor, knit sweaters for a long time, hold children and do other domestic work that requires forearm and wrist activities, the epicondyle of the humerus, which is a centralized attachment of tendons, can be strained and stimulated. This can cause chronic aseptic inflammation around the epicondyle of the humerus due to the accumulation of strain over time. In the mild case, you cannot wring a towel, and in the severe case, you may feel pain in your forearm and elbow when lifting a briefcase or holding a kitchen knife, and you may feel weakness in your grip and fall off easily. How to treat tennis elbow?

And to local brake, pay attention to rest. In the chronic stage, in addition to local braking, rest, protection, physical therapy, pressure massage and oral non-steroidal anti-inflammatory drugs, the main treatment is local closure.
