Sometimes I start out with a sinus headache (not real bad), but then it turns into a full migraine. You dont have to have aura or nausea with migraines. I usually did, but not always. I always have a throbbing pain though... and it's usually on one side or the other (mine are never across the whole head).
I've never heard of that syndrome either ...but I tried googling Neurogenic Rhinitis... and found this...

It's kinda long, but it talks about the difference & similarities of sinus headaches & migraines. If this is what you were looking for, it might help.
Here's a little bit of what is in that website:
It is now accepted that a considerable portion of headache or migraine patients have rhinogenic symptoms. This so called “neurogenic rhinitis” remains poorly understood but probably represents parasympathetic activation. This prominence of nasal symptoms in these patients often leads to a misdiagnosis of sinus disease in patients who meet the diagnostic criteria for migraine.
