My blood pressure has been high for 3 weeks. It has ranged from 180/116 to 149/105. My medicine was changed 2 days ago but my blood pressure is still elevated. I have had a continuous headache and nausea as well. When I ve gone to the doctor, he does t act as though it s too serious. However, when I get online, I read quite to the contrary. What should I do. It s currently 149/105 with medication. My readings have been 176/111, 180/109, 174/108 and at its highest, 180/116. I am a Caucasian female that is 39 years old. What should I do?
