Ronnie from "Jersey Shore" just survived something more painful than a summer with Snooki -- 10 agonizing days in the hospital with kidney stones ... TMZ has learned.
Sources in Ronnie Magro's camp tell us the 27-year-old got out of a Florida hospital Wednesday after undergoing two surgeries to treat kidney stones ... and more.
Ronnie initially went in for the stones, but we're told docs discovered he was born with a hereditary disorder that's also fouling up his kidney function.
Doctors still haven't cleared Ronnie to fly -- so he's stuck in FL for the time being.
Btw, we're told Sammi "Sweetheart" was with Ronnie for his entire 10-day hospital stay ... so they probably broke up at least twice.
