Thanks Oak and jes - it's definitely not a stress fracture, and I'm still hoping for "just really annoying muscular pain and not a tear or major injury" They claim to be making me an appointment with an orthopod next week to see if we can figure it out.

In the meantime, I did commute to work and have been walking, and am going to be kayaking on Sunday. I'll probably go swimming to keep me from going nuts until someone tells me what an acceptable level of activity is... it seems that the weight bearing stuff (running) is the big no-no, and cycling may be okay (but isn't always pain free). I'm really hoping this is just something that massage and lying low will fix.
