The Agony of De-feet

So frustrating with the 2012 creeping up on me.  I am once again side-lined by my heel spur and plantar fascitis.  I was doing very well until yesterday. I was diagnosed in November, babied it, did exactly what the doctor recommended and started training again.  It was going very well and I was able to run 5 miles again.  Added to that was the excitement of planning my 2012 calendar.  Dates filling in, responses back from race directors, opportunities to speak to women about early detection.... all good.  And then, BAM!  Limping, hobbling, crippling heel pain again yesterday. 
Back to the doctor today for another cortisone injection...gosh, I hate those things.  Holding the assistant's hand like a baby, I might have uttered a curse word or two.  And now, more rest, more ice, more time away from training.  Maddening, really. 
I have to stay humble, rest my body and take it as it comes.  All I can do is what is recommended but it is frustrating for me.  In the meantime, lots more planning to do.  My goal is 11 new states this season so plenty of logistics to focus on, even if I can't physically prepare.  That's the update.  Send me lots of healing thoughts please.
