Shin splints are caused by fatigue and trauma to the muscles and tendons in the lower leg and ankle area from the excessive force exerted during activities like running and dancing. Athletes, runners, dancers, and aggressive walkers are most at risk. Shin splints can be avoided by using good quality shoes, gradually increasing exercise intensity, taking rest days, warming up, and watching for proper form. Overuse from hard surfaces, uneven ground, increasing exercise too quickly, or worn shoes can also cause shin splints. Treatments include resting, icing, anti-inflammatory medication, arch supports, exercises, compression sleeves, and elevation.
