Coccyx pain

Hi everyone I gave natural birth almost 7 months ago to my 3rd baby. Postpartum has been harder this time round as I have painful coccyx pain in my tailbone. It’s affecting my day to day life, whether I’m standing or sitting or lying down. I’ve been to the drs few times, they just say it will go away on its own due to the muscles moving around since giving birth or to have physio. Anyone experienced this and how did it get better for you?
