Recently, I learned that I have a mild high blood pressure (125/87 in average). Then, about 3 weeks ago I experience my first headache after orgasm. This headache becomes longer in hours up to 12 hours now. Sometimes on toilet when I try to push my stool out I felt sudden pressure up in my head, and my BP was 165/110 for a minute then decreased. Are this still in the normal range? Or in the danger zone? Thanks a lot.
