I sometimes feel dizzy/lightheaded/faint, very weird sensations for hours or even the entire day.. I dont think i suffer from panic attacks anymore the ones where u breath like crazy and go nuts. Its more of a subtle thing that lingers even when i try or believe im remaining calm. Can anyone relate? People who arent overly anxious but still get these symptoms almost like they were subconcious? Do you think its a real medical condition causing this? I am 25 yrs old,, blood test has come back normal, except my C02 levels were slightly low
