Cankles (aka Tibial Periostitis)

This month I have spent about $300 in physio and massage therapy.  What am I?  The Imelda Marcos of sports injuries?  It's egregious, this amount of money.
I'm all over the place with this injury.
Take "injury".  If you have an "injury" because you were somehow "injured" you take care of that injury.  That injury befell you or was foisted up on you and therefore you are not - to some degree - responsible for it.  You resent it, you regret it, you want to take care of it and you don't want to experience this injury again.
Case in point: I did not attempt to walk my 85 lb German Shepard/Husky on a leash while riding my bike downhill... a second time.  Thank god my Dad was a lifeguard and had some first aid training and allowed me to bleed all over the couch and cause my mother to go a very funny shade of pale instead of making me go to emergency for stitches.
Additionally, after the seven stitches I incurred to repair the damage after I attacked the dashboard of our car with my face, I really took a liking to seat belts.
I also haven't tried to pierce a hole in sandal buckles with an exuberantly sharp pair of scissors again, nor have I recently tried to launch myself off the back porch onto the clothesline under the assumption that it would fashion as some super cool zip line.
Now change "injury" to "sports injury" and you have an entirely different beast.
You have a relatively well read, articulate, logical (mostly) thinker that has an x-ray after her first marathon because she can barely bend her knee afterwards, swears her first is her last, finds out she got into Boston and keeps on running.
I have been in physio for runner's knee, for chronically rotated hips, been given a myriad of exercises for a weak core and glutes, bought a foam roller and most recently an elastic band for resistance training.
Last year I dropped out of my favourite half marathon because it was two weeks after the Edge to Edge (where I really and truly destroyed myself) and it hurt to walk.
Lying on my physio's table two week's ago I asked her "so when you say 'I can't run' what do you really mean?".
It's amazing, really, when you take a step back and try and look at it objectively. 
Here is the conversation that occurs daily in my tiny pea brain betwixt my logical and illogical self.
"You're hurt.  You're weak.  Just take a few months off and get your issues straightened out and you'll come back strong and healthy."
"But it's Boston."
"You've already run Boston."
"But it's Boston."
"The physio says you risk bone fractures if you continue."
"But I can still get back, right?  There's still time?"
"There might not be more time.  You might have to accept the fact that you're injured."
"No.  That's not an acceptable answer.  I just need more drugs/massage/physio/ultra sound/strengthening and/or stretching exercises and possibly another apparatus and it'll be fine."
"You have a cankle."
"I thought Hilary Clinton was bringing those back."
"If' it's a stress fracture the physio says you'll be out for six weeks."
"I read somewhere about these injections you can get into the injured area that lets you run the race..."
To sum up: I have run nine marathons which have taken a significant toll on my body which is directly evidenced by my increasing propensity to end up with injuries and in physiotherapy as time progresses, the most significant one being the one I am dealing with currently.
To sum up: if I can get in for an x-ray this week and the results are negative I can maybe go for a six to ten miler this weekend and then I should be able to go the 21 slated for next weekend and then I can go to Boston.
