Post partum pains?

I’m 2 1/2 weeks postpartum via 2nd C-section… my tailbone started hurting today!! It feels like I have to poop but nothing comes out of course. I can barley sit down cause it hurts bad. Anyone else experience this?!

Little backstory; had no bowel movement trouble since being discharged ( I pooped regular the day after going home ), never took stool softeners either…
