This color change associated with slight burning could be a mild case of CRPS (complex regional pain syndrome) which previously named “RSD”. See https://neckandback.com/conditions/complex-regional-pain-syndrome-crps-reflex-sympathetic-dystrophy-rsd-causalgia-neck/

This also could be some residual from the cauda equina syndrome.
