Patient: Sore elbow, had a closed injection, 2 months later, and then again. Hospital Pain Clinic: Since tennis players are prone to humeral epicondylitis when playing tennis, humeral epicondylitis is also commonly known as tennis elbow, mainly due to the force of playing tennis or often carrying heavy objects in daily life, or excessive hand force, resulting in soft tissue damage to the humeral epicondyle and its adjacent forearm. The disease is often ineffective with medication, plasters, and topical drugs. When the disease is short, local sealing is effective. When the course of the disease is longer, due to the high muscle tone of the affected part, only local sealing combined with small needle knife release can achieve better results. After treatment, the affected hand should be given adequate rest for half a month to a month and excessive strain should be avoided in the future. Overexertion after treatment is a major factor in the recurrence of tennis elbow.
