I am 37 weeks pergant and about a week ago I woke up with a terrible pain in my right rib. Everyday this pain seems to get worse, and normal activities seem to get harder to do. The pain feels like I m being stabbed with a knife. I have been to an OB doctor who says that it seems like it would be floating ribs. But the pain never let s off or gets any better. I have been having a really hard time breathing,walking,sleeping,using the bathroom, getting dressed, just at life in general. Any ideas of what this could be?
