Hi Doc, I'm a 33 year old healthy male, avid runner, 20-25 miles a week. I've been suffering from what I can only describe as constant soreness and fatigue in my lower body. Even if I take a few days off from running when I then go out for a run my legs and hips just feel tight and fatigued. I take good care of myself, eating healthy, stretch, strength train. Could there be a medical reason for my fatigue? I have thought about going to see my doctor but I'm not sure what he would do. No other symptoms I can think of besides stress and anxiety but I've had those since I was 20. What are some medical conditions I could research to see if they match my symptoms?View Thread
