Venting... new cholesterol issue

[Crankin]

OK, I have always had a high level of "good" cholesterol (HDL), slightly above normal total cholesterol (down from a higher #), and average "bad" (LDL) cholesterol. In the past year, I have made a concerted effort to eat more nuts, olive oil, and salmon/tuna. I also have cut my carb intake.
So, I went for my physical last week and got the results of my blood work via a phone call from my new doc, who is supposedly, a wellness oriented physician. When I went to the exam, once she heard about my lifestyle, she didn't have much to tell me! Anyway, my HDL is now freakishly high... 107 (above 40 is considered good), an unheard of number. It was 81 last year. However, the bad news, is that my total cholesterol has gone from 217 to 278, which may have been caused by the increase in HDL, and not the most concerning. My LDL (bad cholesterol) is now 163, up from 130.
On the phone, she said "Don't worry, I am not putting you on medication. We will talk about lifestyle changes." Giving her the benefit of the doubt, I said, "Do you remember who you are talking to? What else exactly do you think I can do?" I suggested maybe eating grass and exercising 7 days a week? She said no.
So, she wants me to go back and get retested in 6 weeks, as it might be a lab error. We will take it from there. I also got a "You *are* 58 years old." .
Everything I read says there is just no agreement about how much the effect of good cholesterol fights the bad. Most specialists would not put me on statins. I have no real family history of early heart disease (before 45 for men, 55 for women). My dad had a heart attack at 83, got stents, etc. after 60 years of smoking and no exercise (he is thin, though). My mom died at 67 of liver disease, though she did go on blood pressure meds in her late fifties.
No one else (grandparents) have a history of early heart disease. My paternal grandfather had a heart attack around age 55- 60 (?), but he smoked and was overweight all his life.
I have always been freaked out about heart disease. The thing is, I am allergic to IV contrast dye, so I can't go have a stress test with dye, unless I want to risk a reaction. Of course, I will await the results of the re-test, but I am thinking of going to the cardiologist at the Brigham that DH went to, to get a second opinion. Yes, this is what drives up health care costs, but I don't need special approval and I don't really trust any local physicians.
