In the last few months I ll have a split second that my head feels odd, unfocused, for want of better words. Recently, I sometimes awake w/ a headache & then my head feels odd all day, not dizzy & unbalanced, but kind of dizzy. Been under stress lately, due to husband w/ MCI dementia & his recent surgery for a different problem. Meanwhile, I ve had to assume charge of the finances that he always handled. I m 74.
