Coronation Street 's Paul Foreman will be left shaken, as he learns he may only have three years to live next week.
The character is told he may be suffering from limb onset motor neurone disease, ahead of his MND diagnosis in upcoming scenes.
Paul is left visibly distressed as he learns of his possible diagnosis, after months of symptoms including issues with his hand and being able to grip things.
It comes after his recent GP visits over his shaking hand, with him wrongly believing it was the result of an accident after he was knocked off a motorbike by Carla Connor.
While he did have minor injuries, Paul believed his hand issues were down to the crash only for it not to improve after treatment.
In scenes to air on Wednesday night, Paul heads back to his GP after undergoing more tests due to the lack of improvement in his hand.
As the doctor reveals he is being referred to a neuromuscular specialist to explore the issues further, he's told a possible diagnosis could be limb onset motor neurone disease.
Asking why he has yet to find out what is wrong, Paul asks in a clip for Wednesday's episode: "What about the symptoms I've been getting?
"The weird feeling in my hand, not being able to pick things up. It's not getting any better, it's keeping me from work. I need the money so I need to get this sorted."
The doctor says: "I do understand your concerns Mr Foreman, but I need to refer you to my colleague who’s a neuromuscular expert to confirm a possible diagnosis."
As Paul says: "Diagnosis? Of what?" she replies: "The symptoms you have been experiencing are very common with limb onset motor neurone disease. I'm not saying that’s definitely what it is but we just need to be sure."
Paul then asks what symptoms it could trigger over time, to which the doctor says: "If it is limb onset MND, over time there would typically be a gradual but increased loss of muscular strength and coordination, and in the latter stages an inability to breathe unassisted."
As Paul stares in shock and fights back tears, he asks if there is a cure and the doctor advises there is not, leading to Paul asking how long he has left to live if he is diagnosed with the condition.
He is told: "Generally speaking following a diagnosis, the life expectancy of 50 percent of people with MND is less than three years."
Pau actor Peter Ash recently spoke about the distressing storyline, ahead of his future exit from the ITV soap.
Peter said: "Paul is completely blindsided by the diagnosis and he decides to keep it from his family and friends as he tries to come to terms with the news.
"I knew very little about MND before embarking on the storyline and I am hugely grateful to the MND Association for all their help and support.
"For any actor playing a role which examines a real life issue or condition there comes a huge sense of responsibility and we are aware that some people watching this storyline are experiencing it in reality, it is their life."
Coronation Street airs Mondays, Wednesdays and Fridays at 8pm on ITV1 and ITV X.
