The tendon pain on the top of running heel may be caused by Achilles tendon injury, Achilles tendon peripheral inflammation, metatarsal inflammation and so on. 1. Achilles tendon injury: If the patient suffers from Achilles tendon injury, such as strenuous exercise, running, long jumping, etc., resulting in Achilles tendon tear or strain, or even acute injury, leading to pain in the tendon above the heel of the patient’s running foot. 2. Periarthritis of the Achilles tendon: If the patient carries out loaded exercise, resulting in rapid flexion and extension of the ankle joint, the Achilles tendon will also be subjected to strong force at the same time, and the blood vessels in the muscle will be squeezed by the prolonged and repeated pulling, resulting in the Achilles tendon being partially damaged, which will lead to the tendon pain on the top of the heel when running. 3. Inflammation of metatarsal bones: when there are traumas, metabolic diseases, inflammatory diseases, etc., it will lead to the damage of the heel bones, resulting in the pain of the tendon above the heel when running.
