A smashed foot may be a simple soft tissue injury or there may be a fracture. The methods to reduce swelling and pain include physical therapy, medication and surgery. 1. Soft tissue injury: first of all, it is recommended that the patient should be braked to avoid secondary injury; secondly, it can be treated with ice compresses and the affected limb should be elevated; after 72 hours, it can be accelerated to reduce the edema by using hot compresses, massage and physiotherapy; if the pain is obvious, it can be relieved by taking Meloxicam, Loxoprofen and other medicines to alleviate the pain. 2. Fracture: after being smashed, patients need to further check the foot X-ray to make clear the fracture situation. If the fracture is in good alignment, it can be given to manipulation and fixed with plaster or support; if the alignment is poor across the joint surface, surgery is recommended, such as Kirschner’s pin or small steel plate and other fixation. For the same disease, patients with different physical conditions and at different stages of the disease, the treatment methods are different and should be standardized under the guidance of a doctor. All of the above medications should be used under the guidance of a doctor, avoid self-medication.
