Lower back

Been there, done that. Had back surgery 11 years ago. Im 5-8 and weighed 180 at the time. I try to keep my weight around 160 now.

The two things that I would say are

stretch - low back, glutes, hamstrings, quads.

lose weight. Change your eating habits and walk 2 miles a day at a brisk pace. Doing some ab work would be a good idea too.

Greater flexibility, more core strength, and putting less of a weight burden on your spine can only help. If you've already done PT then I'm sure they worked flexibility and core strength. Continue that, but add a weight loss element to it. Set a goal to drop 40 pounds and see how you feel.

Techdawg is right. The weight is likely the cause. I wish someone had told me 12 years ago to put the fork down.

The stretches in these videos were godsend to me. Hope they work for you, lower back pain is a bitch.

It is going to be a journey, but as mentioned, 1st is lose the weight. Get a doctor's advice on lifting with your medical condition, and get some instruction on proper lifting form. You will eventually need to build those back muscles up so it quits hurting.

It will probably be a two year journey if you can begin lifting in the next few months.

But most of all, let us know your progress and Good Luck!

Suffered from it for 25 years and had some new painful symptoms this year. It can be treated with PT, chiro, yoga, Pilates, massage, the right work out routine etc. but you’ll have to get in better shape and it sounds like you’ll need some bending and lifting restrictions and modifications with your job
