A lot of people think the pain comes from the spine when it’s actually just the muscles that run along the spine. A common cause of lower back pain is weakened muscles in the lower back due to a sedentary lifestyle. That causes instability and a reduced ability to deal with stressors that normal muscles can usually deal with without issues.

So I’m guessing that that is the issue here, although I’m making some assumptions here about the average Lemmy user :)
