So, I went to see the doc for a second time up in Provo this morning, and he stuck huge needles in my lower leg, made me run for a mile on a treadmill, and then stuck more huge needles in my lower leg. He said I tested for chronic compartment syndrome. The kicker, though, is it's in my lower left leg between the shin and the ankle (just above). The docs in the clinic have never seen it there before, so they're consulting a specialist to see if I need surgery. It requires going in and cutting the fascia to release the pressure, then stitching it all back up. I Googled pictures of this procedure and fainted.
In the meantime, he said if I'm up to the pain, I can keep running for my marathon. So, the training goes on. In fact, I think even if he does tell me to do the surgery, I'll run the Marathon in May and then go under the knife. Who needs summer vacation anyway.
