I have severe blood pressure phobia. It started when I was about 22... I had my BP checked and it was a little high. The doctor didn't even bat an eye, and I largely forgot about it.
Fast forward to 2009. I got a job where I have to get regular physicals. I had a panic attack when I saw they were checking blood pressures, and it was like 150/90 something. A few months later I went to the doctor about it. At office it was 150/100 and he said I had hypertension, and prescribed medication.
I took that for about a year, until I moved and switched doctors. I actually relocated to a city with a Mayo Clinic nearby, so I went to a hypertension specialist there (nephrologist). He told me I did not have high blood pressure, to stop monitoring it, and to essentially stop worrying about it. He said my height/weight combination (5'11" 155lbs), age, and activity level (regular long runs), combined with my history of anxiety disorder, fit the profile for white coat hypertension.
I get annual physicals and both doctors have also said I do not have hypertension, even though at the office it is usually high. When I check it at home, it is normal. I had to throw my monitor away because I would check it 20-30 times per day.
However, I still have the phobia surrounding it. I can't even check it at the grocery store without my pulse skyrocketing and BP rising. I just checked it today at the store and my pulse jumped to 123, and BP was 150/90 something. A few minutes later it was down to 123/83.
This really tears me up and makes me feel stupid, weak, and defective.
