thorough checkup with all my concerns addressed

January 13, 2020 8:22 PM

My blood pressure was high. I didn't feel well. After talking with the Dr. and him telling me if "I didn't but down the cookies, cake etc I was going to be on dialysis" my blood pressure was even higher! Maybe that kind of approach works with some patients but I do not respond well to being scared. One good thing is I was given an antibiotic for a sinus infection and I am feeling better.
