Neven Ciganovic was being filmed by a documentary crew from British TV network Channel 4 when the side-effect from the surgery triggered the rare condition.
According to Neven, it was during the surgery that he was diagnosed with priapism - an unwanted, long-lasting and painful erection that is not accompanied by sexual desire.
"I was in Iran for rhinoplasty for the documentary British Channel 4 is filming covering my life,” the 45-year-old said.
We did not record the surgery but only the consultation sessions with the doctor. They gave me general anaesthesia and I reacted badly to it."
He said: "I'm currently residing in Belgrade hospital since Friday. Unfortunately, I don't get analgesics because they do not give them to patients here, so I continue to suffer.
"I have to be at the hospital for five more days."
Thankfully, the wannabe star revealed a further operation has relieved him of his priapism, though he will not be fully recovered for several months.
Neven admits to having more than a dozen plastic surgery operations, three on his nose plus procedures on his lips, stomach and chin.
"I look forward to a movie about myself. Channel 4 dedicated a whole episode about me. I think this is a big deal and I hope this is the start of my international career."
