5 Years Later(!)

Might as well give a little update - The compartment syndrome symptoms have never returned.  While I had some other issues further up with the hip, it never seemed to be related to the fasciotomy, but rather to congenital anatomy that just isn't so great (if interested, feel free to look up femoral acetabular impingement ;).

You might have trouble with the split if you have FAI!

The only thing I notice is a slight weakness in left calf stability - If I enter a contest on who can stand on their left foot the longest, I will probably lose.  It doesn't really affect day to day functionality though.  

My advice is still the same as it was - If the issues are really localized to the calf and you test positive for compartment syndrome, get an experienced surgeon and do the fasciotomy.

However, surgery is still surgery.  Be diligent about ruling out confounding factors before going under the knife. Get second opinions.  Always get second opinions.
