Clinical causes of plantar center pain are as follows: First, plantar fasciitis: the starting point of the plantar fascia is in the heel bone and the termination point is at the base of the toe bone. If the usual excessive weight-bearing walking, such as frequent up and down stairs, climbing or long-distance running, will cause an increase in the load on the plantar fascia, which will cause gradual strain on the plantar fascia, so there will be a sterile inflammation of the plantar fascia, manifested as pain and soreness in the plantar center of the foot. Second, flatfoot syndrome: the patient has a collapse of the arch of the foot, and the load on the plantar fascia will be greatly increased. At this time, under the normal physiological amount and activity, plantar fascia strain will occur, which is manifested as pain in the plantar heart of the foot.
