Ric Flair is praising the doctors who "brought me back again" -- saying it's a "miracle" he survived a terrifying medical scare earlier this month ... and he's got the $1.8 MIL bill to show for it.
In his first video since leaving the hospital last week, the 70-year-old apologized for not speaking out sooner ... but says his vocal chords have been sore from having a tube down his throat.
But it didn't take long for Flair to start screaming and "woooing" again while explaining how he almost DIED for the second time in just 2 years.
