How does a PT who understands pain react to an “injury” while working out? Part 5

I’ll answer some of the questions I posed in my own personal low back “injury” story.
Why did you decide against doing pull ups?
After feeling intense 9/10 pain after deadlifting and limping while walking, I know my system is really sensitive. That means my system will likely over react to physical stimuli. The thing is, with this new pain, I don’t know what physical stimuli my system can tolerate or not. That’s why I started experimenting on the turf as soon as I felt the pain (I talked about this a few days ago). I needed to find out what my body can tolerate so I can still exercise at my limit. If I’m doing pull ups, it’s very difficult to slowly grade that exercise. Meaning, if I jump up and try to do a pull up, I am now holding up 230 lbs instantly. I cant start at holding up 10 lbs and slowly increase the body weight I am pulling up (there are machines that can assist with this though). So instead I went straight to the lat pull down, which is a similar motion but opposite. Instead of pulling my weight up, I am pulling a weight down from a machine. With this exercise, I can start at a much lower weight and assess how my body reacts to this physical stimulus with a much lower risk of feeling more pain and exacerbating my already sensitive system. If it feels good, I keep going or even increase the weight, if it feels bad, I decrease the weight. One of the biggest problems with patients who have a sensitive system is they go too hard too fast and don’t give their new sensitive system time to adapt to a physical stimulus. Instead, they go right back to a weight they were doing before they hurt themselves and increase their pain. This can exacerbate their system more and now, that person has to lift even less weight in order not to exacerbate their pain. This cycle goes on and on until one day even lifting the weight of their own arm or leg becomes painful and they have to find a way to perform a less physically demanding exercise than lifting their own arm or leg, which is not as intuitive as decreasing a weight on a machine. ← that’s a very common history of a patient in chronic pain.
