A self-confessed plastic surgery addict in Croatia has been left with a permanent and painful erection after surgery went wrong.

But 45-year-old reality star Neven Ciganovic has not been scared off going under the knife again, despite the horror.

He was undergoing a nose job in Iran when the anaesthetic triggered the unfortunate reaction. The surgery was being filmed for a documentary on his life.

Erections lasting longer than four hours are deemed a medical emergency.

He's been recovering in a hospital in Belgrade, Serbia.

"Unfortunately, I did not receive analgesics because they do not give them to patients here, so I continue to suffer," he told media.

Ciganovic has had more than a dozen operations - three on his nose plus procedures on his lips, stomach and chin.
