35w1d and I'm so uncomfortable!! 😭😭😭

Linda • 23, married, 3rd pregnancy, but first baby that stuck 😊🌈🎀
I feel like my ribs are overlapping in the center. And I have constant mid back pain because my ribs are pressing against a nerve/muscle/something. I've been in constant pain since I was 25 weeks. But the pain in the center of my ribs just started this morning, and I just wanna cry!! 😭 I don't know what to do!!! 
Any suggestions on what could help? Even temporarily??
