Which kind of specialist to approach for wonky ribs specifically?

Hi! My biggest struggle lately is my right ribs, particularly lower ribs. They feel painful, stiff, and generally out of whack. One seems sunken from the front and a bit "poky" out the back. I'm constantly squirming, shifting, and deep breathing to produce movement and audible clicks there.

My dream is for a doctor to be interested, say, yes, your ribs are weird, and loosen them up/"put them back" or show me how. It's there a particular sub-specialty who really cares about ribs, that I should seek out, that anyone's had luck with?

(I've had a general PT before, but he was way more interested in my weird-looking shoulder blade, even though that doesn't hurt 🤣.)

Thank you!!
