Rib pain!

Victoria
I'm 31w 5d and have been experiencing an EXTREME amount of rib pain for the last 3 weeks or so. My OB said that unfortunately it won't go away until after he's born :( It's like a throbbing/burning feeling and sometimes it travels to my back. Anyone else have this? How do yall relieve the pain? I've tried massage, warm back, a heating pad (on low), ice, stretching...nothing is working! 😭
