Looking for correlation between complex PTSD and body pain

I am very interested in the connection. I definitely think my complex ptsd has the potential to spiral my physical symptoms or make physical ailments that would be no bid deal for most people a lot worse for me. And for tangible, logical reasons such as poor sleep creating a barrier for adequate nervous system resets and healing. Increased muscle tension from anxiety exacerbating injuries. Poor attention/avoidance causing lack of self care such as water consumption, eating healthy, procrastination, clumsiness, etc. It does not explain everything but I do think there is something to it.
