A sprained foot that feels painful and uncomfortable only the next day is a non-serious ligament or muscle soft tissue injury. If it is a serious injury, such as fracture or dislocation, there will be obvious pain and obvious swelling at that time, so pay attention to observe whether there is obvious swelling in the local area. If the local swelling is obvious, routinely improve the foot X-ray examination to understand whether there are fractures and other conditions. If the pain is only soft tissue injury, the local area can be coated with Fotarine to relieve pain. There are also ointments that can be used to activate blood circulation and resolve stagnation, such as pain relief ointment treatment. Temporarily avoid walking and local exertion, appropriate hot water can help relieve local pain.
