I suspect your shoes. I used to work in housekeeping, btw, so I know just how hard it is! But check out your shoes. You should have high-quality, supportive, roomy shoes for this kind of job. Sometimes just a new pair of athletic walking shoes, if they are the right fit, will help.
If just getting new shoes doesn't help, I'd suggest you visit a foot specialists (who may or may not be a doctor) to have your feet evaluated and see whether you need any special inserts or supports in your shoes for doing your work.
The next thing I'd suggest is that you do some exercises to (a) strengthen your legs, and (b) strengthen your abdominals and core muscles. If legs are weak, the back has to take more stress than it's comfortably made for. If the abs are weak, then the same thing happens.
Also, make sure that you know the proper way to lift, and that you don't bend over more than you have to. When cleaning a tub, for example, it's better to have a knee pad and get down on your knees than it is to bend over the tub from a standing position.
It might also help to wear a lumbar support belt on the job, depending on your tasks. You can get one at most drugstores. But, you might want to check with your doctor or a good chiropractor as well. Sometimes there is a structural reason.
I'm not a doctor or a health professional, so this is not medical advice. It's just things I would suggest based on my own experience.
Good luck! And when you get home after work, elevate those feet!
