If a patient has a sprained foot for one year and still has pain, it may be because the joint capsule, ligaments and fascia of the patient’s ankle have become more seriously adherent and local calcification has occurred. During the treatment, the patient should try to reduce the activity of the ankle area, and pay attention to keep warm, often use warm water to soak the feet, or put safflower, panax ginseng, astragalus and other Chinese herbs in the water, which can activate blood circulation and remove blood stasis, tonify the qi and benefit the blood, analgesia and circulation. If the patient has a clear pressure point in the ankle area, closed injection can also be used locally.
