The following four types of drugs are used externally after a fracture: 1) ointment to activate blood stasis, reduce swelling and pain; 2) external application of Chinese herbal medicine to connect the bones and tendons; 3) external application of Chinese herbal medicine to nourish the liver and kidneys and strengthen the tendons and bones; 4) local swelling and pain disappear in the late stage of the fracture, but the movement of the joint is impaired, and the joint becomes stiff and straight, so you can use local external washing or collapse of Chinese herbal medicine to relax the tendons and activate the tendons, or do local fumigation treatment. It is good to improve the function of the joint. If the fracture becomes painful again when the weather changes, you can use topical topical lotions with medicines that dispel rheumatism and open the meridians.
