The pain on the inner side of calf tibia is considered to be related to trauma, inflammation, tumor growth, overwork or cold. 1. Trauma: If the calf shinbone is damaged by external impact, such as fracture, it will easily cause pain and even induce motor dysfunction. 2. Inflammation: If inflammation occurs on the inner side of calf shin bone, such as fasciitis or periostitis, the stimulation of inflammation will easily cause pain and even local swelling. 3. Tumor growth: If there is tumor growth on the inner side of the shin, such as bone tumor, it will easily stimulate the local pain receptors, thus triggering pain. 4. Excessive fatigue or cold: if long time weight-bearing activities or strenuous exercise, it may trigger the symptoms of inner calf pain, and if the inner side of calf shin is exposed to cold stimulation for a long time, resulting in localized cold, it will also trigger pain. If the symptoms of inner calf shin pain are more serious, you need to go to the hospital for treatment, to prevent the later trigger of motor dysfunction.
