I am a 47 yr old african american woman. I had a laproscopy 4 days ago (my BP was great). When I went for my pre-admission tests last wk my BP was very low 86/54. I've been diagnosed with hypertension 6 yrs ago. I am now taking Losartan - however, I just took my BP today and it read 145/101. Should I go to urgent care or ER?
