If the pain is caused by external force, it may be a metatarsal fracture of the dorsum of the foot, which can be clearly diagnosed by taking X-ray film. If a fracture of the metatarsal bone occurs, it should be repositioned by manipulation, and local ointment for blood circulation should be applied externally, such as golden yellow ointment and blood pain relief ointment, and at the same time, it should be fixed by braces to prevent dislocation of the fracture site, or oral bone-setting drugs to promote healing of the fracture site as soon as possible. If the fracture does not occur, a large portion of the plantar fascia may be torn, which may also produce more severe pain. Patients with osteoarthritis or chondromalacia of the plantar region may also experience pain after external force.
