A doctor in the room described his injuries as being hit “on the right thigh [with] two bullets” and “on the left thigh two bullets,” adding that his “left tibia was fractured.”
In an address to the nation, former Pakistan Prime Minister Imran Khan revealed details of his attack after being shot during a rally.
Mr Khan claimed he was shot four times during a protest march in Pakistan on Thursday, with two bullets striking each of his legs.
A doctor in the room described his injuries as being hit “on the right thigh [with] two bullets” and “on the left thigh two bullets,” adding that his “left tibia was fractured.”
The doctor said there was a fracture on Mr Khan’s right leg and near the main artery there were some bullet fragments.
“If it was hit there, there would have been a lot of bleeding,” he said.
“We took these four bullet fragments out but they did not touch any major structures.”
He added: “Once I recover, I will once again come onto the streets.”
The former prime minister gave an interview to Sky News two hours before he was shot in which he said he was hopeful there would not be violence during his march across the country.
Asked if the prospect of violence worried him, he said: “I’ve been on the road for six months now, what I’ve seen I’m confident that I will be able to direct it through elections. I will be able to direct this through elections and bring about a change. But the other possibility is, you would not want it to go the other way.”
Footage from the scene captured what local media is citing as the gunman, who appeared to escape as members of the public tried to take the weapon off him.
Police are questioning the alleged attacker, who appeared in a video saying he carried out the shooting and acted alone.
The cricketing hero-turned-politician – who has been calling for new elections since he was ousted from power in April – has been delivering impassioned speeches at gatherings across the country.
He was six days into a march from Lahore to Islamabad in his push for radical change when the shooting took place.
Following the shooting, Mr Khan’s supporters staged nationwide protests, blocking key roads in major cities and sometimes clashing with police.
His party has called for the protests to continue until its demand for political change in Pakistan is met.
“Today, after Friday prayers, there will be protests across the country, which will continue until Imran Khan’s demand is met,” Asad Umar, a close aide of Mr Khan, tweeted.
Prime Minister Shehbaz Sharif, Mr Khan’s successor, condemned the shooting and has ordered an immediate investigation.
