i used to have it pretty badly. the best thing you can do for it is to stretch it out. A physiotherapist would be better for you to see. They will help balance out the muscles and give you some good stretches.

Make sure to stretch the rest of your legs too, especially your hamstrings. With jogging problems can often stem from core weakness. So it doesn't hurt to strenghten your core as well.
