If you have chronic pain, do you remember the exact moment it started, and did you think at that time that the pain might be long term?

I have a healthy fear of chronic pain, as in I actively try to avoid doing stupid stuff to and with my body. Lifting with my back, for example.
Yesterday I was bent over, shopping stuff in a tote on the floor, and something gave in my back where I’ve never had cause for concern before. I thought, “I hope to flock that this isn’t it. It’s incrementally better today, so I think I dodged the bullet, but this question was generated.
