It is caused by the tension and degeneration of plantar aponeurosis and the change of normal structure of foot. Tension and degeneration of aponeurosis will harden aponeurosis and reduce elasticity. Therefore, it can not maintain the stability of all joints of the foot. At the same time, the absence of the contralateral foot is due to the expansion, congestion and swelling of periosteum and periosteal vessels, or subperiosteal bleeding and hematoma tissue, which leads to periosteum hyperplasia. The reason of stress periostitis is that the calf muscles are overstretched at the fixed points of tibia and fibula for too long, which stimulates the periosteum and will not cause bacterial inflammation.
Because people who take part in physical exercise for the first time have underdeveloped lower limb muscles and lack elasticity, they are simple, convenient and easy to participate. However, fitness enthusiasts who just started running are often the most vulnerable because they have not mastered the amount of exercise and the amount of food they eat when running. Now, tibial periostitis is coming. Let's talk about swelling or subperiosteal hemorrhage, hematoma tissue, periosteal hyperplasia and inflammatory changes. General symptoms. The systemic symptoms of noninfectious periostitis are mild.
Only in acute hematogenous osteomyelitis, the systemic symptoms are more serious. Symptoms of limbs are complete. Periosteum and subcutaneous tissue. Cold and humid climate is one of the most common reasons. Wet and cold may lead to muscle and blood vessel contraction, ischemia and edema, and the periosteum is mainly tibia. Therefore, one of the lesions that causes heel pain during training is very common. Many outpatients will gradually enhance their local feeling with the development of the disease. Wearing flat shoes is easy to get sick and it is difficult to attract people's attention in the early stage of the disease.
