9. Chest Pain.
If you have chest pain that radiates down your arm, to your neck, or back, then you need to consider your symptom to be a medical emergency and seek help immediately. If your chest pain comes and goes then do not take this lightly either; this could be a sign of an unusual blood pressure. Chest pain is not something that causes high blood pressure and high blood pressure does not cause chest pain, but these two typically go together in a cluster of serious symptoms. If you notice that you have chest pain, you should make sure to talk with your doctor to see what the cause may be.
