Headache Variant. Anterior ethmoid nerve syndromes is a series of symptoms resulting from irritation of the terminal branches of the anterior ethmoidal nerve. The referred pains arising from this nerve are chiefly of the sinus type but may also take the form of headache, sometimes of a migrainous character.
Pain over sinus. This is a condition in which, you're a pain directly over the sinus region. Usually from the bridge of the nose, to the cheek. The pain is usually constant and excruciating. It is due to irritation of a branch of the ethmoid nernerve. Nerve. Supplies sensation for this reason. In my opinion yes really a type trigeminal neuralgia, but the irritation is at a branch of the nerve near it's end.
