Did you find out anything about your diastolic? I am having blood pressure problems also. I get spikes, but the diastolic numbers are much worse than the systolic.
Typical numbers for me are usually 125/94 135/95 145/102. At night when I am relaxing I am 117/85 however I have gotten numbers such as 110/70 but it's quite rare and that's when I am in bed laying down. Any activity I do my diastolic jumps up. When my medication is increased I can get numbers like 98/85 and i feel horrible, out of breath and often my pulse rate wil increase to 110.
What are your numbers? The goal is to keep the difference between your systolic and diastolic pressure at 40 points or more.
Let me know and perhaps I can point you in the right direction.
