Hi, I used to be an amateur runner, hiking aficionado. Over the last year I've had increasing pain in my right lower leg. With 5 minutes of running, 1/2 hour of downhill hiking, or 4 hours of flat walking, I get a horrific pain. The pain is in the posterolateral aspect of my calf (the outer backside), just below my fibular head (the smaller bone, on the outside of the leg, a couple of inches below the knee). At first it is an ache, and it feels it will work itself out. Then it becomes tighter and tighter until it is a really painful deep pain, and starts hurting all the way down my leg. First, what the heck is it? Second, how do I fix it? I have to fix this so I can get back in the mountains!
