Should I skip a session?

Hey all- I usually go to yoga about 4 times a week. I broke some ribs 2-3 years ago and it took a while but they seemed to heal fine. Then yesterday, I’m doing something as stupidly mundane as vacuuming under a bookshelf and I felt a ‘pop’ and long story short, I think a rib or two slipped. It’s nowhere near as painful as breaking them was- thank god- but it is sore enough that I am having trouble sleeping and it feels like there might be something out of place that shouldn’t be. I think I may have to go in and get them re-checked, but my insurance is horrible so it might be a little while to see if it fixes itself on its own first.

Is it still safe to practice with modifications, or should I wait until I get further guidance from a physician? Are there specific poses that might actually help a slipped rib?
