so I fell down some stairs about 2 years ago at our old apartment and contused my back at that time. took about 6 months to get back to some sort of normalcy. I'm a nurse and work 12h shifts and I'm on my feet about 10 of those hours and with lifting and moving patients I've got lower back pain to begin with. I heard that with pregnancy things start moving around and softening down there in preparation for baby and my coccyx/sacral area has been very painful lately and when I lay down on my back and need to move to a side its very painful I just feel like the bones are loose down there. I plan on seeing a chiropractor post delivery but is this feeling normal with pregnancy? I knew my back pain would get worse I just want to see if its a "normal" type of back pain during pregnancy 😅
