I went to the doctor and my blood pressure was 164/100 I have always had low pressure 117/78 never high.  He checked it again a little later and it was the same.  He told me to wait a week and get it checked again.  Should I be concerned?  I have been under some pressure changing jobs and all.  Could this be a cause?

Stress management is the key in your case. So better to consult psychiatrist and get done counselling sessions. Try to identify stressor in your life and start working on its solution.
