This was at PT. Heavier lifting than normal. Headache came back after this, for the rest of the day! Such a bummer! Gone by the following day, but I'd thought I was good for medium intensity. It was disruptive enough to my work day (had to lie down) that I need to be careful w medium intensities still.
The not-so-bad news is I'm at least keeping up with my oura ring's activity goals that include walking, so some baseline activity's happening. Foot has been ok walking everywhere I need to go so far! It's usually 15-20 min max, like to lab, but has also been fine on a walk or two up to an hour.
