After the foot was broken, the surface of the foot was swollen, and a lump appeared, considering that the local injury has bleeding formed hematoma. If the foot is not more than 24 hours old, the local area can be given ice packs in time to reduce swelling and pain and reduce the possibility of the mass. 24 hours later, you can choose to soak in hot water, which has the effect of activating blood circulation and promoting the dissipation of the mass. If the swelling is obvious, it is necessary to improve the X-ray examination in time to understand whether there is a combination of fractures and other conditions. If the hematoma mass is formed by simple soft tissue injury, it can be sprayed with swelling and pain aerosol. In addition, you can take drugs that activate blood circulation and remove blood stasis, such as Salvia tablets. Pay attention to rest and temporarily avoid long-distance walking, walking around and prolonged standing and sitting to help the swelling subside, and eat more yam and tianqi as appropriate.
