I haave been having trouble with my blood pressure. I am 62 yrs old and have a family history of heart disease.My pressure dances all over the map. It can be 122/45 and then 136/ 56 or 122/41. It also at times will be 156/70or 170/70...not sure what is going on. My pulse ranges in the 52 to72 range. I use to be 120/80 for years but in the last 3 years it is a yo yo....When I go to the doctor I start to have' white coat sydrome' and my diastolic never dips as low as it does when I am just at the drug store taking it. I am visiting my doctor to check my high pressure (2nd viist). I do not feel dizzy while awake but do get dizzy in bed at times. I have degenerating disks in my neck and think that is what the dizziness is from but now starting to wonder? If I go on meds. for hight pressre won't this also make my diastolc go further down?
