Try not to read to much into it. I have high blood pressure and was told by my doctor to NOT go by the machines they have in pharmacies and stores because they are not very accurate. Plus if you have been walking around shopping it is natural for your heart rate to be elevated and therefore could give you a high reading. You are really young to have high blood pressure problems. But if you are nervous, go to your doctor. They will most likely tell you to purchase a blood pressure cuff and take readings 1-2 times a day for a couple of weeks and then come back in. That is how they can tell if you have a problem with hypertension. Good luck!
