The most common reason is that after prolonged walking or strenuous exercise, the ankle joint muscle strain or ligament damage occurs, resulting in localized soreness or other uncomfortable feelings, especially when standing and walking, the symptoms are obvious, but the symptoms can disappear when resting in bed. For the above situation, first of all, the cause should be removed, avoid prolonged walking or strenuous exercise, local hot compress treatment, more foot soak, massage or moxibustion treatment, if necessary, with oral non-steroidal anti-inflammatory and analgesic drugs symptomatic treatment. The second cause may be due to lumbar disc herniation, which usually leads to soreness or radiated pain in front or behind the ankle after the nerve root is compressed by a herniated disc in lumbar 4-5 or lumbar 5-sacral. In this case, it is recommended that the patient actively improve the CT or MRI examination of the lumbar spine to make a clear diagnosis before taking the corresponding treatment measures.
