Flat feet are related to genetic factors, tibialis posterior tendon insufficiency, degenerative changes, etc. Usually patients are able to be corrected by medication and surgery. For asymptomatic flat feet, no treatment is needed. If the patient has pain, reduced walking ability and other symptoms, then the patient can seek medical treatment and wear a brace to improve the situation. Those with pain can also take non-steroidal anti-inflammatory drugs such as ibuprofen and indomethacin as prescribed by the doctor. For those who are not satisfied with conservative treatment and have serious conditions, they can seek medical treatment through surgical procedures such as soft tissue transfer and repair, medial displacement osteotomy of the heel bone, and subtalar joint braking. In daily life, foot massage can also be performed to improve the flexibility of the foot arch and relieve plantar pain. Patients can also choose shoes with good arch support and avoid wearing shoes with heels. It is recommended that patients with flat feet should actively cooperate with the doctor for treatment, and should also visit the doctor regularly for review. Appropriate foot soaking in warm water at night can help promote local blood circulation and improve foot fatigue.
