After ankle sprain, the sequelae are mainly in two aspects: the first one is habitual ankle sprain, which is mainly caused by not taking sufficient brake rest after the first sprain, resulting in ligament relaxation. In terms of treatment, you should try to wear high-top shoes to protect the ankle joint, and try to wear ankle protection when you go out, which can effectively play a role in stabilizing the ankle joint, and pay attention to avoid walking on uneven surfaces, otherwise it is easy to have another ankle sprain. In the second case, the pain and unfavorable activity of the ankle joint is mainly due to the fact that the ankle joint has not fully recovered from the sprain and formed a sterile inflammatory lesion. It is easy to feel pain in the ankle joint when you are cold or tired. You can use hot water or Chinese herbal medicine to scald the ankle joint, such as Xanthium, Cao Wu, Chuan Wu, Bonesetter, Tao Ren, Safflower, Mugwort, and Gui Zhi, which can effectively warm the meridians and disperse cold, relax the tendons and channels, and activate blood circulation and remove blood stasis. Frequent scalding can help eliminate local inflammatory lesions and reduce pain and unfavorable movement symptoms.
