Off topic?? Lower back pain after pregnancy

Hey all! So I’m not sure if this subject is good to post under this topic but i need help (also will post under different topic) anyways! I had my son a year ago and ever since I had him I had this extremely bad lower back pain during and around my period only. I can’t sit or lay down. I can’t pick up anything (or my son) and I can’t bend over. Sometimes it’s hard to actually go to work and work because of the pain (I work at a amazon moving boxes) It feels like my back is gonna snap when I try to do anything. At first I thought maybe it’s because I “don’t” do anything at home, so I started stretching and became more active and guess what I still have that horrible pain. About 2.5 years ago though, I did have a muscle spasm in my lower back from working at another warehouse and throughout my pregnancy my back would hurt but not as much. I havnt gone to the doctor because I know for sure that they will say that it’s normal and to just do stretches and stuff. So what are you’re guys ideas/thoughts I need help
