I am 73 years old woman, my blood pressure today was 122/70. About a month ago, I was 140/90 and was put on a blood pressure pill and a week ago on a small diuretic. Since starting to take the diuretic, my body temperature has been 95.7 to 97.5. Been very weak. My doctor feels I picked up a bug and just coincidence since just starting the diurectic. Should I be concerned over the lower blood pressure, lower body temp., weakness etc.?
