Imran Khan smiles during an event in Islamabad. File

Imran was speaking at a fundraiser for the Shaukat Khanum Cancer Hospital in Karachi when he spoke about his fall from an elevator a few years ago.

"It was such an injection that the pain went away entirely," he said. "My whole world changed. I started seeing the nurses there as hoors," he said.

The prime minister said he was in deep pain due to injuries after he fell from the stage while campaigning during the 2013 election. But the injection by the Shaukat Khanum Hospital nurse not only removed the pain but enabled him to make a speech as well, which he couldn't remember later. However, he said that when the injection's medicine faded, he started to feel the pain again, Geo news reported.

"I pressed him [Dr Asim] so much. I told him to give me the injection again, for God's sake," said the prime minister. "I even threatened him by saying I will deal with you. Give me the injection. However, he did not."

In 2013, Imran sustained serious injuries on his head and back after falling down from a lifter. The incident occurred in Lahore, a few days before the general elections were contested.
