I'm trying to figure out whether or not to hyphenate a new medical-related phrase, "post birth control syndrome."
I know Post-traumatic Stress Disorder is hyphenated, but that seems to make sense because "post-traumatic" on it's own defines the state of the condition.
"Post-birth-control" doesn't feel right as "birth control" as a phrase isn't hyphenated.
So do I do "post-birth control syndrome" or "post birth control syndrome" and why?
