Doctor's answer (1)
Dr. Lin Yunfei
Peritendinitis of the Achilles tendon is mostly caused by excessive lower limb loading, such as prolonged running and jumping, which can subject the Achilles tendon to strong or repetitive, prolonged stretching. This often leads to fatigue-related injuries. Clinically, patients typically experience pain and a sensation of tightness in the calf after physical activity. It is recommended to reduce exercise intensity, ensure adequate rest, and soak the feet in warm water at night, which can help alleviate symptoms of Achilles peritendinitis.
