...but there are many cases where the word "pain" isn't quite sufficient to describe what's going on. I was once stuck in a hospital for a period of about 7 days flat on my back after a surgery. I have some arthritus in my lower back resulting from many years of construction, and after several days the pain caused by immobility became excruciating. I didn't want to take a painkiller for various reasons, so I lay there and suffered. At least that's the word that best describes what I experienced from my POV. I didn't have any ideas that what I was experiencing shouldn't be happening, but when pain becomes agonizing and prolonged, most of us would describe that as a form of suffering.
Psychological suffering (ie: "I shouldn't feel this way" or "this shouldn't be happening") is like adding an unnecessary layer on top of whatever is physically happening.
