2. Clinical manifestations: the vast majority of flat feet do not have obvious symptoms, a small number of patients can be manifested as the pain and swelling of the inner arch of the foot, and physical examination can see that the longitudinal arch of the patient’s foot is flattened or disappeared; while patients with hallux valgus will have more obvious hallux valgus manifestations of the outer ankle, and the Achilles bone can have compensatory outward movement, and it may even cause the talus bone to be subluxed and other manifestations.
