Lisa Riley shared an update on an arm injury she described as 'horrendous' and required surgery.

The actress, 49, who plays Mandy Dingle in ITV soap Emmerdale, joined Kaye Adams, GK Barry and Denise Welch on Friday's episode of Loose Women.

The episode began with Kaye Adams asking the star: 'Lisa, what's going on with the arm?'

Lisa replied: 'Well, it's like these chairs, these stools, that we've got here. 

'Five weeks ago, just before I was about to go to New York, I was filming Emmerdale - with the court week that's about to be on next week.

'And I went home, said to Al, "Look babe, I'm tired. Put some soup in the microwave"'.

She went on: 'The stool I've been sat on for seven years - literally with a long cardigan - I think had been over polished.

'I sat down and whoop, I became a human sledge. Landed really badly.

'I had to have surgery on it, here I am week five now. So please say your prayers for me on May 6, I'm back with the specialist and [the cast] is going to come off.

'They let me travel - I was more worried because I was flying to New York literally four days later.

'So they've put this expandable cast on and it was Easter can you tell, went for an Easter colour.

Lisa went on to describe the actual wound as 'now like a dog bite', adding: 'Obviously I'm going to have rehab now, physio as I move forward.

'It's been horrendous, I still can't move anything.'

Asked by fellow panelist Denise whether Lisa believed she 'fell over' or 'had a fall', the actress confirmed the latter.

She said: 'I had a fall, I did have a fall.'

Joking that she was sober at the time, the soap star explained that her fall caused serious damage to her thumb, which led to her needing an operation to repair her Ulnar Collateral Ligament (UCL) at Leeds General Infirmary.

Surgery-requiring damage to the UCL is caused by tearing the ligament on the inside of your thumb's main joint.

In her post, Lisa cheerfully posed for a selfie post-procedure alongside her surgeon, Dr Thornton, and was also pictured leaving the hospital with her arm in a sling.

Alongside her Instagram post, the actress praised the NHS, branding the service 'incredible' and thanking the medical team who provided her care.

Lisa wrote: 'OUR NHS @nhsengland IS INCREDIBLE…….I have to massively thank my specialist surgeon Mr Daniel Thornton at LGI LEEDS hospital and all the beautiful team, every single one of you who treated me this afternoon

'I had a very bad fall over the weekend (no I'm sober) no drunk jokes-it was my extremely slippy breakfast stool and a woollen cardi-my left thumb took all of it.

'So today hence the massive damage I have had my operation, surgery, treating my UCL in my Thumb repaired. (sic)'

Elsewhere in the Loose Women episode, Lisa talked about supporting her family though her mother's death from breast cancer.

The panel had been discussing Coronation Street legend Beverley Callard's ongoing cancer journey. 

Meanwhile, the actress' beloved mother, Cath, sadly lost her battle with cancer back in 2012.

Lisa shared: 'With my mum, obviously, I've spoke on here - she passed away from breast cancer.

'From initial diagnosis, she survived and was doing great - and then the last year and a half, when the secondary came, we knew it was the end. 

'I had to be there - I was doing Calendar Girls - I left the job straight away to be my mum's full-time carer.

'I had to be there for her and I wanted to be there for her, every minute of every day.'

She went on: 'But I can relate to my dad - when we were told, the volume of morphine she was given, because she was in the palliative care stages.

'Dad was in complete denial - he was completely. Me and my brother, who I love to death, he just went insular. 

'I was there for him going, 'I'm here if you want to talk' and he didn't want to and I always describe it as being like the tent.

'That if I didn't stay strong, this tent is going to fall down. Mum was not going to get better.

'At 58 years old dying of breast cancer, so young, I had to keep my Dad high as it were.

'As close as we got to her dying, he still truly believed that she was going to get better, whether that was his way of coping.'

Loose Women airs on ITV1 and ITVX.
