Symptoms include headache neck pain and stiffness and i am constantly tierd?

Can call Dr on video: Normal, healthy people do not have "constant tiredness," without a good reason. One's primary care doctor can evaluate and look for reasons for fatigue, such as infection, anemia, auto-immune disease, mental illness, thyroid problems, cancer, insomnia, etc... Various tests may be needed, depending on one's whole story, and sequence of symptoms.
