Headaches may be among the first symptoms of hypertension, or high blood pressure. This headache is often located at the back of the head and is usually noted upon arising in the morning. The pain is throbbing or pulsating. This headache is worsened by exercise, straining, or stooping, since these activities raise blood pressure. A diagnosis can usually be made by checking the blood pressure, which is measured as two numbers: The systolic pressure is listed above the diastolic pressure. A normal reading might be 120/80 (systolic/diastolic). The number 120 (millimeters of mercury) is the systolic pressure, which may vary with activity, exertion, or nervousness. More >>

GERD is a chronic condition. Once it begins, it usually is life-long. If there is injury to the lining of the esophagus (esophagitis), this also is a chronic condition.
