For sure it was caused by my anxiety, I had a brief experience with OCD. When I was so paranoid about my heart after the surgery when the anxiety was at its all time high, I had about 3 weeks where all I would check my blood pressure with my blood pressure cuff 10-15+ times a day and I would carry it wherever I went. To work, out to eat, anywhere. Luckily I have chilled out and I dont have to take it everywhere I go. I have optimal blood pressure, but I didn't care, I needed to check it, because I felt like if I didnt, I would all of a sudden have high-blood pressure creep up on me if I forgot the cuff at home even just once. Glad thats over!!!!!
