Eamonn Holmes can't walk straight and has to use a crutch, as he continues his recovery from three slipped discs.
The 61-year-old TV presenter has admitted it was "awful" not being able to sleep at night because he was suffering such chronic pain, but he now has steroid injections to help get some rest and is "on the mend".
He said: "It's three slipped discs.
"I actually have to come on here with a crutch, that’s the way I am at the moment.
"I’ve got steroid injections and everything’s OK, and hopefully I’ll be on the mend.
"Chronic pain, no matter what causes it - it doesn’t discriminate between whether you’re young or old, man or woman or whatever.
"I couldn’t sleep at night, I just couldn’t sleep.
"Lying there at night, trying to get to sleep while Ruth was sound asleep beside me. Honestly, it was awful.
"I've got the injections, which have taken away the acute pain and I can sleep and that’s a blessing, absolutely great.
"But the physicality of not being able to walk straight."
The 'This Morning' presenter admitted his lost nerve endings may take a year to grow back, but he is determined to "get fit" again.
He added: "I’m going to embark on a whole rehabilitation programme, I’ll get fit, I’ll get strong.
"It will take a while, but the doctor said to me when you get this your nerve endings die off, but they grow a centimetre a month.
"I thought, 'That's good,' but he said, 'No, it's got to go from your hip to your toes.'
"That's going to be about a year."
Eamonn's wife Ruth Langsford admitted she has felt "helpless" seeing her husband in pain.
Speaking on 'Loose Women', she said: "He's alright, he's here. And it's a long road, we know that.
"It's very difficult seeing him in so much pain. You feel a bit helpless, actually."
Earlier this month, Eamonn - who underwent double hip replacement surgery in 2016 after putting off the operation for 25 years to focus on his career - admitted he has been in tears over his back pain.
He said: "Discs, three of them. Out. It hasn't been a good time. I've been in tears."
