I have had a cold for nearly a week. Cold symptoms almost gone, but started feeling nausea last night and blood pressure has been elevated all day. I m on 50 mg losartin sand 25 mg hydrochlorathiazide a day. My BP was 168/97 this morning so I took an extra 25 mg losartin this morning. It is still 167/95 and I still have the nausea spot below my rib cage. I have no fever. The only heart related issue I have is mitral valve prolapse which is being monitored every 2 years. I m an almost 71 year old female.
