Ay, alam ko yan! A few of us CS moms experienced that rib pain din, kaya hindi ka nag-iisa, usually it's from how your body shifts during recovery or kung paano ka natutulog at nag-aayos after surgery. But honestly, since it's pain on a specific side and you're post-CS, better to mention it sa OB mo just to be safe, kasi gusto natin ma-rule out kung may something else going on o kung kailangan mo ng specific stretches or positioning para better.
