Is it just me or does pain mask make brain fog worse?

i was pulling wires all day today and my lower back kept acting up, low grade nerve pain tbh. had to keep slowing down every few minutes, which is miserable pacing.

i’m usually okay with that physical drain, but by the end of it, i wasn’t even tired from thinking about what i needed to do next. i think trying so hard not to let myself feel pain or fatigue all day just drains my reserves faster than the actual work does.

am i the only one who feels like the cognitive load of ‘hiding it’ is a full-time job itself?
