Pain and discomfort in the middle of the sole of the foot may be caused by plantar fasciitis, flatfoot deformity or other lesions. You can go to the orthopedic department to see a doctor in time, and the doctor will make a preliminary analysis with physical examination. If flatfoot deformity is considered, a weight-bearing x-ray of the foot can be improved to determine the condition. If the symptoms are not serious, you can choose arch support pads for conservative treatment, but if it is a serious flatfoot deformity, you need to undergo surgery if necessary. If the pain is caused by plantar fasciitis, you can appropriately soak your feet with hot water, and local treatment can be combined with creams, such as flurbiprofen babu cream. Pay attention to more rest, temporarily reduce long-distance walking and strenuous exercise, and avoid wearing high-heeled shoes to help relieve pain.
