Shin splints

You just have to wait it out, lay off the exercise involving your legs until they feel better. Then you take preventive measures like shin/ankle stretching and strengthening exercises before and after your runs.

My routine is walking around on the balls of your feet, and then your heels for a good distance, then putting your back against a wall, feet about one foot length away from the wall, shoulder-width apart. Now start doing push-ups with only your heels. I do about 30 of those 5 times, in-between sets of those I walk around my house on my heels some more. Once I started doing this consistently I didn't have shin pains anymore after excessive leg cardio. The exercises them self you'll know are working because you'll feel the tiny muscles on the front of the shin burning up.

Make sure you stretch out your calves a lot. They are caused by the muscles in the calf. So if you stretch them out nicely they will get better xxx
