Yes, please talk to your doc. The damage caused to our organs (e.g. heart, kidneys) by high blood pressure is cummulative over many years, and you may have elevated BP at an earlier age than a lot of folks develop it, so all the more reason to not let this go. When I first started developing high BP, my doctor's advice was low sodium diet, exercise, and maintain a healthy weight. I have a BP machine at home and go through periods when I check it quite frequently, like several times a day for a week or more. I found that lowering the salt in my diet did lower my BP by about 5 mm, which is great. I also take omega-3 fatty acids and try to eat lots of high fiber whole grains, fruits, and vegetables.

Your doctor will find it very useful if you take your BP regularly and then bring in your records to the appointment when you go. This will give him/her a better sense of how high and how real your numbers are.
