Cutting all slop from my diet really helped me. Natural fats and oils, as little carbs and sugar as possible. Last year I thought my spine was fucked. I was terrified I would end up needing surgery, or I had permanently damaged it from work or something, but when I got on a low-inflammatory diet it got way, WAY better. Also if you eat a bunch of beef or use cast iron to cook everything (like I did for years) you might have a buildup of iron causing *some* of that pain.
Going on a low inflammatory diet got my back feeling roughly 60% better and really dialing back my iron intake got me feeling almost completely healed, and I'm pushing 40.
I spent 6 hours bent over the engine bay in my truck the other day doing a water pump and timing shit and at the end of the day i was sore, but the next day to my utter shock, I felt fine. I never would have considered doing that a year ago.
Hope this helps you (or some other anon).
