Richard Lewis, who stars in “Curb Your Enthusiasm,” shared a video on Twitter where he revealed that he has Parkinson’s disease, saddening his fans.

According to reports, the comedian received the diagnosis of the disease two years ago but chose not to make it public until Sunday when he shared the news on social media.

“I have Parkinson’s disease, but I’m under a doctor’s care and everything is cool,” said Lewis, 75, adding, “I’m finished with standup. I’m just focusing on writing and acting” from here on out.

The native of Brooklyn announced in a two-minute clip posted on Sunday that he had finished filming Season 12 of Larry David’s iconic sitcom, expressing that he was “so grateful to be part of that show.”

The conversation turned somber at that moment.

“But you know the last three and a half years I’ve had sort of a rocky time,” the “Leaving Las Vegas” actor said. “And people have said, ‘Gee I haven’t heard from you, are you still touring?’ Well, here’s really what happened.”

According to Lewis, his problems started three and a half years ago when he was on a comedy tour, and he made the decision at that time that he “didn’t want to be on the road” anymore.

“I said, ‘You know, I’m at the top of my game,’ ” the comic said. “After 50 years almost, I’m just going to call it quits.’ And I felt great about that. And then out of the blue, the s – – t hit the fan.”

The comedian stated that he had to go through four surgeries in a row which included back, shoulder, shoulder replacement, and hip replacement surgeries.

There are many more issues to address, beyond what has been mentioned so far.

“On top of that, two years ago, I started walking stiffly, I was shuffling my feet,” said Lewis. “I went to a neurologist, and they gave me a brain scan and I was diagnosed with Parkinson’s disease.”

“Parkinson’s disease is a progressive disorder that affects the nervous system and the parts of the body controlled by the nerves,” according to the Mayo Clinic.

“Symptoms start slowly. The first symptom may be a barely noticeable tremor in just one hand,” they said. “Tremors are common, but the disorder may also cause stiffness or slowing of movement.”

According to the medical site, the symptoms of the neurological disorder tend to worsen as the condition progresses with time.

According to Lewis, the only positive aspect is that he “got it late in life, and they say you progress very slowly if at all.”

Lewis received positive thoughts from his friends and fans on Twitter.

“I love you, Richard! Before I ever knew you, I loved watching you perform,” said “Curb” co-star Cheryl Hines. “You’re just a beautiful person. I hope the love you’re receiving from everyone will continue to make you stronger everyday.”

“I love @TheRichardLewis,” said Ben Stiller, who made an appearance in Season 4 of the Larry David sitcom. “One of the funniest ever. Richard you’re an amazing person and I’ve been your fan since I was about 12 which is a very long time. And we’re both still here! Stay strong.”

Mark Hamill, famous for his role in “Star Wars,” also showed his support by writing: “Wishing you all the best & thanking you for a lifetime of laughs.”

Since the show made its debut in 2000, Lewis has been a recurring member of the cast on “Curb.”

In the show, he portrays a character based on his own life, who is a neurotic and unsuccessful comedian friend of Larry’s and who always has troubled romantic relationships.
