Yes, I agree with you. From my own experience, though, you only really understand if you know chronic pain. Before that, compassion and empathy will help, although they're rare. I heard a story about a woman who broke her leg; it was nearly an open fracture. Due to adrenaline she didn't feel pain at the beginning, and so she refused to wait for the emergency doctor with pain meds. During the drive to the hospital the pain came. I thought someone who knows pain would have chosen to wait for pain medication. Only someone who doesn't know PAIN thinks it won't be so bad.
