What Causes Headaches, Muscle Pains And Dizziness?

Hi. I'm a 18 year-old Chinese girl in Toronto. Recently I've experienced headaches, muscle pains, dizziness, a bit of shortness of breaths/hyperventilation, upper back pains, and pains in the vaginal opening area. Before this I've always been healthy, with none of those problems. I don't drink, smoke, or take any medications. I don't have weight loss problems and have never had sex. Could you help me please?
