I used to be an avid runner in high school and enjoyed the same benefits as you describe, until junior and senior year when I developed a dull aching pain in my lower legs whenever I ran. I began taking a lot of OTC anti-inflammatories to counter it, which worked for a while. After seeing a few doctors, it was eventually diagnosed as chronic compartment syndrome. I've been debating whether to go forward with the surgical cure. It's a tough decision, because the condition doesn't present itself outside of long-distance running, and the surgery is rather invasive. I seriously miss running. For those of you who can run, I strongly recommend it. It can be an immensely enjoyable way to stay in shape.
