Most of the causes of leg pain are that the amount of running exercise increases too fast, without gradual progress, which leads to long-term tension of leg muscles and continuous muscle involvement, resulting in tearing injury of tibia and fibula membrane, periosteum, periosteum vascular dilatation, congestion, edema or bleeding, and periosteum hyperplasia. This kind of leg pain is called fatigue periostitis of tibia and fibula. In severe cases, there is localized swelling on the inside of the calf or above the ankle joint, burning sensation in the skin, weakness in the back pedal, severe pain and difficulty in walking. The pain of backing out is a unique symptom of this pain. When the toe is pushed back, the calf feels pain. In addition, because the ground is hard, the landing action is incorrect, and the buffer is insufficient, the calf will receive a large reaction force, resulting in calf pain.

Those with severe leg pain and small nodules or lumps can also be treated by physical therapy, massage, acupuncture and local injection of procaine. You can stop running. The injured calf can be fixed with elastic bandage for two weeks. Be careful not to rub the pain point inside the calf with heavy hands when the pain occurs, which will stimulate the periosteum to cause reactive thickening and prolong the healing time. In addition, if you run fast after the onset of pain, under the continuous stimulation of this external force, the periosteum will be damaged, which may eventually lead to fatigue fracture. Different from fatigue fracture, fatigue periostitis only feels pain when carrying out weight-bearing activities (walking and climbing stairs).
