OOOOH lol you're looking for specifically post-top-surgery folks, I gotchu. I personally didn't experience phantom limb; however, I did have to "re-train" my brain into recognizing that I take up less space there now (so I can fit into smaller spaces!), and needed to re-map my sensory neurons into understanding where exactly on my body was being touched. That’s normal for big surgeries like that, and was painless for me (it was often a ticklish process though). I hope others chime in?
