Good: Your BP is a dynamic number, fluctuates during the day, related to the situation, emotion,other factors. The machine, technique also matters.

Yes: You have LABILE BLOOD PRESSURE! That is to say that it varies a good deal! This is common and can be treated with some instruction in SELF RELAXATION methods..biofeedback, etc. Read Herbert Benson's classic book "The Relaxation Response" Hope this helps Dr Z
