Q: What's Less Fun Than Running a Marathon?

A: Going to the Emergency Room because of it.

No worries, though friends. Turns out to just be a fracture.  There was some concern it could be Compartment Syndrome, a 'limb and life threatening injury,' but it's just your run-of-the-mill stress fracture.  

If any medical professional tells you they are going to do a 'striker' test for compartment syndrome, put your big girl/boy panties on. That's a doozy.
