<s>[INST] I went to the Dr. on Saturday for a sore throat which was strep. my blood pressure was 140 over 106. I had not taken my bp meds in a few months and thought I felt fine. my bottom number has never been this high. A few days before the drs visit i did have a tooth pulled by a dentist. I didnt know if this was just a one time incidence or if I have something causing this to happen. [/INST] Hi, Any type of mental or physical stress on body may be associated with fluctuation in blood pressure which may be high or low BP. In your case there might be following causes for high BP-1) Part of your high BP problem for which you were taking medicine previously but stopped since few months.2) May be due to present infection. I want to know-1) Since how many years you had BP problem and taking medicine for it.2) Which medicine were you on for high BP.3) Have you stopped BP medicine by your own or after consultation with Doctor.4) Have you regularly checking BP after stopping medicine.5) Presence of illness like diabetes.6) Family history of BP problem. I will advise you to monitor your BP regularly and consult your doctor. </s>
