Hi,
Any type of mental or physical
stress on body may 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.
