Martin Lewis has been left in tears by an "agonising" throat ulcer making it "impossible" for him to do live TV work.
The Money Saving Expert founder hasn't been able to leave the house for the past four days due to the painful condition, and he was forced to cancel an appearance on "Good Morning Britain" this week.
Taking to Facebook, the "Martin Lewis Money Show" star said: "Throatgate day 4. Thanks for all the well wishes. I wanted to give you an honest update as so many of you have been asking and been so kind.
"Sadly, I'm no better - you'll have seen I couldn't do Good Morning Britain today - live TV is impossible.
"Last night I saw a specialist who confirmed I've a large, vicious ulcer in my throat (I won't post a picture of it) - not a cold/flu.
"Unfortunately eating and speaking are truly agonising, causing the left of my face and neck to go into spasm - leaving me close (or sometimes in) tears.
"There is no treatment but to wait, though I'm finding that tough as there's no sign of improvement and sleeping is hard. (sic)"
The 46-year-old journalist - who hosts financial advice segments on "This Morning" - is going to try to film some links for his own Monday show in advance.
He added: "I'm going to go and try and film the links for my Monday show today. I've been given a special local anaesthetic to get me through it (I've been told doing it won't make things worse).
"The team are very considerate - I won't be able to do retakes - and will have to rest 20 minutes before each take.
"I must admit to literally shaking with nerves about leaving the house to do it, but I'm doing it as I want to, as sitting in the house in pain has made me rather low. (sic)"
