Antonio Brown claims the doctor who trashed him for farting during a 2018 appointment secretly LOVED IT ... and AB says he has the texts to prove it.
Dr. Victor Prisk told Sports Illustrated ... Brown was essentially the client from hell when he began working with the NFL star in late 2018 ... he would show up late and didn't pay.
But, Prisk told SI the worst part was when Brown ripped ass in his face during a body fat test -- a fart that was captured on video and featured on TMZ Sports.
