Not really, our brain adjusts to weird stimuli pretty quickly. Sitting slightly painfully your body often ignores it until you try to move again and feel the pain then. Also limbs going numb due to blood loss. I once woke up and tried to get up but something heavy was on my left shoulder making it really hard.

It was my left arm, I didn’t realize I couldn’t feel or move it until I tried to get up, which automatically uses muscles in that arm.
