Plantar pain indicates that there may be plantar fasciitis, plantar soft tissue injury, flat feet and other diseases. 1. Plantar Fasciitis: Walking or standing for a long time will cause the plantar fascia to be stimulated by greater pressure and cause fascial injury, resulting in aseptic inflammation of the fascia and pain in the soles of the feet. 2. Plantar soft tissue injury: Excessive exercise or external pulling will lead to damage to the plantar muscles, ligaments and other soft tissues, causing local edema, fibrous degeneration and other changes, which will stimulate the plantar and cause pain. 3. Flat feet: due to congenital developmental abnormalities or insufficient strength of muscles and ligaments in the arch of the foot, affecting the normal physiological structure of the arch of the foot, resulting in the collapse of the arch of the foot and irritating the soles of the feet, causing pain, numbness and other uncomfortable symptoms. If you have pain on the bottom of your foot, you should pay attention to it and go to the orthopedic department of the hospital in time to get a clear diagnosis and follow the doctor’s instructions.
