Symptoms of arch collapse mainly include pain, swelling and abnormal gait. 1. Pain: The pain is often located in the medial plantar aspect of the foot, hindfoot, posterior medial aspect of the foot or lateral aspect of the ankle joint, which is prone to progressive aggravation and may be aggravated after prolonged standing or walking, so that the pain extends along the medial side of the heel bone and forward to the plantar aspect of the foot, especially after waking up in the morning or after resting. 2. Swelling: Swelling occurs near the painful joints, such as the navicular tuberosity of the foot is prone to swelling. 3. Abnormal gait: The patient’s foot pain and arch collapse can cause a decrease in the ability to run or walk in daily life, and gait abnormalities, such as an out-of-place gait, will occur. 4. Pain and abnormal gait can affect other joints of the body: for example, excessive pronation and internal rotation of the affected foot will cause compensatory pronation of the knee joint and compensatory external rotation of the hip joint, which in turn can cause pain and arthritis in the lower back, hip joint, knee joint and other parts of the body. It is suggested that patients should avoid sedentary and overwork in daily life, pay more attention to rest, and when the symptoms are serious or do not get better for a long time, it is necessary to consult a doctor for examination in time.
