> This is commonly referred to in the medical field as referred pain. To be a bit pedantic I don't think this is correct--"referred pain" specifically refers to a quirk of the nervous system where acute pain is perceived in a spot that is NOT actually undergoing the harmful stimulus, as when a heart attack causes pain in the arm (rather than around the heart/chest) or acid reflux in the esophagus manifesting as pain/pressure in the chest (rather than the throat). What you're describing seems more like your back is actually traumatized and therefore in pain, but there's some underlying chronic issue outside the back which has, over a longer period of time, led to said trauma. In other words, referred pain means trauma in locus A causes pain in locus B, whereas what you're talking about is trauma in locus A causes trauma in locus B causes pain in locus B.
