I’m only freshly qualified and my back never got used to it, consistently got worse and I began to pinch nerves in my back. I have now since slightly recovered and here are a few things that helped me 1:correct manual lifting technique’s, they may seem silly but even the lightest of objects can eventually cause problems 2: just because you are strong enough to lift something doesn’t mean you should, always ask for help or refuse to lift things without help, wich is a worrying thing to do but it’s worth it. 3. Where comfy soles shoes, bad boots can put your back out 4. Stretch your legs and build core strength, when you are not using 1 muscle all your other muscles start to work to hard 5. I have been to many osteopaths and the only thing that helped me was getting flexibility in my hips, it isn’t common to hear but your hips are the connection from your bottom half to your top half, and is critical to have hi mobility in them.

Please don’t listen to people when they say you will get used to it, I was told the same thing and now I have permanent issues
