I m a very healthy 57 yo woman. For the past month, I ve had low grades headaches (previously very rare), mild constant nausea, gas (am both burping and passing gas). I feel mildly unwell, which is new for me. No change in diet or exercise habits. Take only transdermal estrogen. Nonsmoker, rare drinker. Mild stress occasionally when I have work deadlines (not stressed now). Worth seeing my doc soon or should I ride this out for another few months?
