My 45 Year Old White, Otherwise Healthy Girlfriend Has Been

My 45 year old white, otherwise healthy girlfriend has been experiencing the following: Intense pain behind the right eye, accompanied by pain at the back of her head, accompanied by upper neck pain. This condition is not severely present all the time, but when she has an episode it comes on fairly quickly (within an hour) and is also accompanied by anxiety or a feeling of unease. I am worried because today a new symptom, a feeling of nausea (not vomiting) presented itself. This condition has been worsening over the past few months. Should I be worried? Well, I am worried... but should I be emergency room worried? btw, she has a mild deviated septum.
