First, I am not a Doctor, but I play one on TV!
I am assuming that if you know you have high blood pressure, that it was diagnosed by your Doctor? If so, his advice should be taken if the condition is serious, and merits immediate attention!
If the condition is not an immediate concern, as in your BP is only slightly inflated, I would consider getting advice from a second Doctor as well. BP meds have lots of side effects, as well as physical limitations.
Fortunately, many times it can be controlled with diet, excersise, and lifestyle modifications ( Avoiding stressful situations, deep breathing techniques, meditation, etc...) designed to help you lower your BP.
No matter what path you choose to treat your high BP, the worst thing you can do is ignore it! I'm the almost the same age as you, (42) and I have high BP, and have had two heart attacks and a triple bypass already! I never went to the Doctor, even though there is a family history, and if I had taken care of myself and seen the Doctor, I would be much better off today than I am.
Best wishes to you, and may your health remain good!
