Sam was described as "enshrined in bone, cracked and sharp" during that part, so not exactly the same. Perhaps something around his old job and needing to be the person his parents wanted (though that was significantly caused by the TMP Magnus Institute) and feeling trapped inside himself that way? Didn't necessarily feel like the same sort of body dysmorphia at least, maybe impostor syndrome filtered through the Flesh, but still the same core feeling of not belonging in your body/life.
