Swelling after muscle trauma may be due to local muscle injury resulting in edema, or local hematoma, or other problems. It depends on the degree of local swelling and pain. If the local swelling is extensive, it is still necessary to improve magnetic resonance examination to determine the degree of muscle injury, whether there is a combined hematoma, whether it is accompanied by fracture and other serious conditions. For simple minor muscle injury with swelling, you can choose conservative treatment, such as local blood-activating drugs, such as swelling and pain aerosol spray, you can also apply pain relief cream, pay attention to rest, and when the pain is more obvious, you can take oral fenbendazole. For severe muscle injuries with extensive hematoma, surgery should be considered when necessary to remove the hematoma completely to reduce the risk of infection and help recovery.
