After receiving a Parkinson’s disease diagnosis and undergoing four surgeries, comedian Richard Lewis announced his retirement from stand-up.

The 75-year-old “Curb Your Enthusiasm” actor, renowned for dressing in all-black and performing while exploring his neuroses, released a video to Twitter on Monday outlining his many medical conditions.

He said he had undergone shoulder and hip replacement procedures and had “a sort of rocky time” for the past three and a half years.

He also underwent a brain scan since he was walking with shuffled feet. He was given a Parkinson’s disease diagnosis by medical professionals. He stated, “Fortunately, I discovered I had it late in life, and they say you progress very slowly, if at all. I’m also on the correct medications, so I’m fine. I’ve completed stand-up. I’m just concentrating on my acting and writing.”

“Robin Hood: Men in Tights,” “Leaving Las Vegas,” and “Vamps” are just a few of Lewis’ big-screen credits. He has also made appearances on numerous TV shows, including “7th Heaven,” “George Lopez,” “BoJack Horseman,” and “Dr. Katz, Professional Therapist.”
