The results from the MRI are in. Here is what the Dr. said via email:
The MRI shows changes in the fibular shaft consistent with a 'stress response.' These are the beginnings of what we would see with a stress fracture, but no fracture was seen. There were no other soft tissue abnormalities, including tendonitis, that were seen.
Right away, I would start taking calcium 1000mg and vitamin D 400 IU daily to help with bone growth. As far as training, we need to talk about specifics and goals for your current race schedule, so I agree we should touch base by phone.
Good news, bad news?? Doesn't sound horrible, but explains why my leg still hurts. I will be talking with my Dr. soon about what I can do. Guess it might have been a smart idea to stop running for a little bit. 26 days left till Boston Marathon.
