I have the same thought, it must be as it's accounted for in medical practice, but also how would I know? I only have my subjective experience to go by.
I think it is important to accept everyone's own experience of their pain though, I have no idea what someone else is feeling even if I have experienced the same event. Their experience and what they feel could be vastly different, our nervous systems behaving vastly different. It is not a morale failing to feel and be affected by pain.
I have been told that I have that, but I don't think it feels any less painful. It's not possible to know. I feel I am just a little accepting of it.
Broken femur is almost a different league though.
