After a broken foot, you can choose Yunnan Baiyao aerosol, which can help relieve the pain after local spraying and allow the skin temperature around the joint to drop, as well as help vasoconstriction and reduce local blood vessel rupture and bleeding, which can help relieve the swelling caused by the siege. However, it is not possible to rely on Yunnan Baiyao aerosol alone. A brace or cast for fixation of the broken foot is needed to keep the injured soft tissues in a stable, relaxed and rested state to avoid aggravation of the injury and to prevent habitual broken feet, also called habitual ankle sprains. After the acute phase, you can take Yunnan Baiyao capsules orally, which also have the function of activating blood circulation, relieving swelling and pain, reducing the local symptoms and swelling, and promoting the recovery of the injured position.
