Recently I have fatigue, lightheaded, disoriented, back pain and back pain. I went to my monthly visit to my primare care doctor and my blood pressure was 80 over 32, It has been ok since (2 weeks). I had had blood work done in his office a week before my monthly visit. He did say anything was wrong with it. I called him to explain how I felt and he recommended a brain scan. My next appointment with him is on Dec. 3, 2016 and my brain scan is sceduled for Dec. 27, 2016. I really do not want to wait that long feeling like this. Should I call him again?
