Last night and this morning Ive taken my blood pressure a few times only to discover each time that the diastolic reading was 107. (Full reading: 167/107. Am I in immediate danger with a diastolic reading that high over the course of last night and this morning?
The mentioned blood pressure is high in both context, systolic and diastolic.  At this pressure lifestyle modifications like salt restriction and exercise will not be able to normalize it, though not imminent danger, however I will request you to consult your doctor at earliest, so he can start a medication for the same. I will recommend you to start medication first once the pressure is controlled, and you change the necessary lifestyle Modifications we can title down the dose.  Also, don't be anxious, as anxiety will push it up further disregards
