Stephen Fry broke his leg, pelvis and several ribs after falling off the stage at London's The O2.

The 66-year-old actor had been speaking at CogX Festival in September when he took a tumble as he left the stage and suffered horrific injuries.

Speaking to Claudia Winkleman on BBC Radio Two, he said: "I was doing an event at the O2 arena. I did my hour after delivering this lecture, turned to go off stage and didn't notice I was walking off a part stage where there was nothing but a six-foot drop onto concrete.

"I broke my right leg in a couple of places, my pelvis in four places and a bunch of ribs. I'm now fine. I'm now without a stick.

"It's been fine so far but I feel slightly self-conscious without the stick. The cane, more than helping me walk, is a flag to everyone around. I live in London where the pavements are absolutely packed. So [this time of year] you get slightly nervous with people stopping to take pictures of lights, or the [pavement] is slightly slippy."

Fry was treated at Queen Elizabeth Woolwich hospital and revealed his injuries were so severe that he was offered painkiller Oxycontin after the accident.

He said: "[It's] not a famous hospital but doing extraordinary work every day. They were brilliant to me. They are under a huge amount of pressure but they delivered everything I could have possibly wanted.

"The first night they took me to hospital, the nurse brought out this little pot with pills in and I asked what they were. She said that's Zolpidem to help you sleep, this is this, and this one is for your pain. It's called Oxycontin.

"I said what? That's the highly addictive opioid drug that is basically behind the opioid crisis. So I said no, I don't think I should have that.

"Anyway the next morning, the surgeon comes round and said oh you've been refusing the pain killing. And I said it was very kind of you, but I'll put up with a bit more pain.

"He said you misunderstand I didn't prescribe it for your sake at all, I prescribed it for the sake of the NHS.

"He said [there are] two scenarios: one you don't take this pain killer which is the best pain killer yet to be devised for the kind of pain you are in. For six or seven weeks, you'll lie without being able to move and what will happen to your muscles is pretty sorry, and your recovery will be months and months.

"Scenario two: you take the pill and probably tomorrow afternoon I'll send round a couple of burly physios who will get you on your feet, put you in crutches and you'll shuffle in some pain for about five minutes and then be anxious to get back to bed, but the next day a few more shuffles, the next day a step or two, you will sit in a chair for half the day and feel a little more human and you will have reduced your recuperation time massively.

"So, these pills are not just for your comfort they are there to speed up your recovery to save the NHS money."

And, Fry revealed that despite his injuries he feels lucky that it wasn't more serious.

He said: "The person treating me told me he was treating a patient who had fallen on the same day as me, half the distance, and would never walk again. So I really praise my lucky stars. If it had been the spine or the skull who knows."
