Sports injuries are damage to the body that most often occurs when people are being active. While they may seem minor, when left untreated, they can lead to misalignments in the body. For example, if you injure a foot, you may favor that foot. So you step harder on the other one, creating an unnatural and potentially damaging way of walking. If not corrected, the other foot will also become painful, as well as the back, knees, and even the head. It’s all connected.
