Sharon Osbourne, 68, was left with dizziness and sickness after contracting Covid-19 last year.
The music mogul and former X Factor judge was secretly hospitalised with the virus before recovering away from husband Ozzy Osbourne, 78.
Speaking for the first time in detail about the ordeal which left her with longterm changes to her senses, Sharon said: "I’m fine now except that I’m still very tired.
"I nod off at ridiculous times of the day.
"I’m good. I went through all the symptoms, eye ache, body ache, dizziness, sickness, all of it."
She added to her The Talk co-hosts Sheryl Underwood, Carrie Ann Inaba, Elaine Welteroth and Amanda Kloots: "But you know there’s people who are much worse than I got it.
"They have it much worse and I just think I came out very lucky.
"I still can’t smell very much or taste very much."
In an announcement on December 15, Sharon told her fans she had been struck down with the virus but was on the mend.
Posting to her 2.3 million followers, Sharon wrote: "I wanted to share I’ve tested positive for Covid 19.
"After a brief hospitalisation, I’m now recuperating at a location away from Ozzy (who has tested negative) while The Talk is on scheduled hiatus.
"Everyone please stay safe and healthy."
Luckily, Ozzy, who suffers with degenerative disease Parkinson's, tested negative for Covid.
Previously talking about living with the illness, the Black Sabbath icon said: "Well the one questions from me was, ‘Is it a terminal illness?’, and the guy says, ‘No, but life is’.
“It’s just another thing on my plate I have got to deal with. I’m not in the slightest worried about it.
“I’ve not got any secrets. The initial shock is I’ve got Parkinson’s.
“Nobody knows what the f*** it is. I didn’t know anything about it apart from the name.”
Sharon added in January, "It's not a death sentence but it affects certain nerves in your body. You have a good day, a good day, then a really bad day."
