The main purpose of cold compresses is to reduce blood flow and reduce exudation by causing local vasospasm, thus helping to reduce swelling. After the sprain, if the injury is more serious and the swelling is more obvious, you can take oral Mai Zhi Ling, which is to promote the reduction of swelling. In addition, after 24-48 hours after the sprain, you should consider taking the blood-strengthening drugs, which can accelerate the local blood circulation, promote the repair of local soft tissue damage, and also promote the local blood flow to prevent deep vein thrombosis, etc. Therefore, you can use the appropriate ice to reduce swelling and blood-strengthening drugs to treat the symptoms.
