I have not done a very good job of sticking with one of my implicit goals: stay injury-free.
In fact, I haven't been able to even log mileage at this point. After a few weeks in physical therapy, I've actually uncovered a second issue--looks like piriformis bursitis. I guess that means that means that between that and the sacroiliitis, I'm doubling down on the sciatic nerve. I went to the doctor today, just to confirm via multiple X-rays (I'm glowing now) that I don't have any stress fractures. The doctor's preliminary thought is no, but he's sending to the radiologist to double-check. If symptoms don't improve with physical therapy, I'll have a bone scan to have a closer look.
In the meantime, I have several strengthening and stretching exercises to do, plus I can continue the pushups routine.
