I am 56 yr old female,164lbs, my blood pressure was 92/62, I do feel a little light headed and also a headache, is this something to worry about? My blood pressure usually runs 113/77. I am also in stage 3 kidney disease. Do I need to be concerned about this also I have a low grade temp. Which that is a temperature for me ,if It is 99.5 something is going on,because I never run a fever unless I am so sick
