Common causes of Achilles tendon pain include acute injury of the Achilles tendon, overuse, Achilles tendonitis, etc. Symptoms can be relieved by moderate massage of the painful area according to the cause. 1. Acute injury of the Achilles tendon: Repeated stress on the Achilles tendon by the body during exercise, such as frequent jumping, may lead to acute injury of the Achilles tendon and symptoms of pain. If the patient has a partial tear of the Achilles tendon, the affected foot can be plantarflexed, gently pressing, rubbing the swollen and painful parts, and massaging the calf triceps muscle belly, etc., to reduce muscle relaxation and promote proximal Achilles tendon retraction. 2. Overuse: Overuse of the Achilles tendon due to overloaded sports, long-term running and other activities may lead to chronic injury to the fibers within the Achilles tendon. Massage can be used to relax the calf triceps muscle, so that the symptoms of tension and stiffness in the calf triceps muscle can be improved, and at the same time alleviate the symptoms of Achilles tendon pain. 3. Achilles tendonitis: the Achilles tendon degeneration caused by age, chronic injury, cold stimulation and other factors, resulting in aseptic inflammation of the soft tissues in the area of the Achilles tendon, the symptoms of Achilles tendon pain will occur. The pain can be relieved by thumb flicking, together with massaging the acupoints around the Achilles tendon.
