Flat feet generally do not require treatment if they do not present uncomfortable symptoms; if they are accompanied by foot pain, joint stiffness, gait changes or toe deformities, they can be operated on. Flat feet are mostly caused by heredity, developmental deformity, trauma, degenerative lesions, etc. Most people have no obvious symptoms, while a few people may have pain, swelling in the arch of the foot, abnormal walking posture, etc. If the symptoms are mild, rest, use of the foot, and other measures can be taken. If the symptoms are mild, rest and use of corrective tools such as arch pads can be used for general treatment. If the pain is more significant, anti-inflammatory and analgesic drugs such as ibuprofen and celecoxib can be used. If the symptoms are more severe, such as heel valgus and tendon dysfunction, surgical therapies such as soft-tissue transfer repair and bony surgery need to be considered. If there are persistent uncomfortable symptoms of flat feet, you should consult a doctor in time and under the guidance of the doctor for regular treatment.
