Shin splints: You could be experiencing shin splints. They can present as soreness to pain on the anterior (front) calf. Shin splints can occur after athletic type activities (walking/running) when a proper warm up or stretching is not done prior to the activity. Shin splints can also be caused when there is an imbalance in strength between the anterior (front) and posterior (back) calf muscles.
