I had my second round of x-rays yesterday. I snuck a peek at them and didn't see anything on them that cried out 'You have a stress fracture!'. I go for another follow-up with the sports medicine doctor on the 18th, so hopefully I'll have a diagnosis then. I've realized what's killing me is the uncertainty... that I can't move forward until I know what's going on and what to expect.
I've also learned that I'm fortunate in that it could be worse. I could have a stress fracture in way worse places, such as my tibia, hip or pelvic bone. Ouch!
I also know what I did wrong to do this to myself. I realized that I've worn my green superfeet insoles since I started running seriously 2 years ago. I was in physio at the time for a back/calf injury and she suggested that I lose weight and try superfeet insoles. That's what I did! So it really was stupid of me to run three times in a row without them, especially a 13K run. Those runs put a lot of stress and contortion on my lower leg muscles, resulting in injury.
I start physio tonight, which I'm looking forward to. I want to use this time to work on my muscle strength and imbalances. And of course, to lose those 10 lbs. that I put on over the past few months.
