Human foot bones are very precise. There are 26 bones, and there are more than 100 rope-like ligaments between the bones to bind them together firmly. In addition to ligaments, there is a fan-shaped connective tissue on the sole of the foot, which is the plantar fascia. It extends from the calcaneus to the five toes, and nets these bones on the soles of the feet like a "fishing net" to maintain the height of the arch and maintain the correct posture. Plantar fascia is like a natural shock absorber of human body, bearing the weight of our whole body and absorbing the reaction force from the ground. When the plantar muscles are violently impacted by external forces or walk for a long time, it often causes local muscle strain and local fascia inflammation. The most common symptoms are heel pain and discomfort. The pain is obvious when I get up in the morning, and it gets worse when I walk too much. In severe cases, you may even feel pain when standing and resting.
The incidence of plantar fasciitis in women is about twice that of men, which is related to wearing high heels frequently. People who love climbing mountains and have flat feet are also prone to this disease. These people should pay attention to warm-up before exercise, choose loose shoes and try not to wear hard-soled shoes to prevent plantar fasciitis.
People who have suffered from plantar fasciitis should first rest more and use physical therapy (such as ultrashort wave and electrotherapy) to relieve pain. For heel pain caused by standing for a long time or strenuous exercise, you can ice your heel 10 ~ 15 minutes. Secondly, the arch pad can be used under the guidance of a doctor, which can effectively reduce the tension on the fascia and reduce the damage to the fascia when the lower limbs are loaded. If fasciitis is serious and the pain is unbearable, you should go to the orthopedic clinic in time. Posterior foot decompression is the main method to treat fasciitis at present.
