Lower back pain

Does anyone have any tips on how to deal with lower back pain?? I’m 8 weeks pp and I’m STRUGGLING. I mentioned it to my dr and he just said “it’ll take some time to get back to fighting strength” and to let him know if I hit 8 weeks and it still hurts. I messaged him yesterday and I haven’t heard back yet, but I wanted to see if there are any at home tips I can try? Right now it’s basically just ibuprofen and prayers lol.

I tried going for walks, but it’s freezing outside so I did a step video, and that seemed to irritate my back even more. I tried yoga and couldn’t get back up off the floor. Took a warm bath and couldn’t get out of the tub without my husband basically airlifting me lol. I’m running out of ideas…

I just want to be able to carry my little girl without tears 😭 Thank you!
