I have been very tired for the past 2 weeks. During this time, I experienced headaches, dizziness, tightness in the chest, shortness of breath. I had my pressure checked this past Monday and it was 160/96. I went to the doctor on Tuesday and my pressure was 140/74. Today, I checked my pressure in the morning and it was 160/96. In the afternoon, my pressure was 154/106. Should I go to the emergency room NOW or can it wait till Tuesday? I live in a rural area, and a doctor is not always available.
