There is usually no absolute fixed time for how long to apply medication after a fracture, usually until the swelling and pain of the fracture are mostly relieved. If the fracture is mild, the damage to the surrounding soft tissues is not very serious, and the local swelling is not very strong, usually 2-3 weeks of early dressing, the local swelling and pain basically subsided, you can stop taking medicine. If the local fracture is very serious and the surrounding soft tissues are abnormally swollen, it must be applied for about 4-6 weeks to completely reduce the swelling. In addition, if the fracture enters the recovery period and the surrounding joints or soft tissues become adherent, if you want to apply the herbal medicine to soothe the tendons and loosen the adhesions, you can generally apply it until the joint mobility basically returns to normal, and then you can stop applying the medicine, which takes about 4-6 weeks.
