“Like two years ago, I had this weird, super rare form of vasculitis that kind of knocked out my vision, my hearing, my balance,” Kutcher said in a clip shared by Access Hollywood.

I don’t know if I’ll be able to hear again, I don’t know if I’ll be able to walk again. I’m lucky to be alive.” After the video went viral, Kutcher took to Twitter to clear up the situation and give an update on his health. “Before there’s a lot of rumours/chatter/whatever out there. Yes, I had a rare episode of vasculitis 3 years ago. (Autoimmune feeling) Immediately after I had some hearing, vision, balance impairments. I fully recovered. All good. Moving on. See you at the 2022 New York Marathon with Thorn,” he tweeted. Before there’s a bunch of rumors / chatter / whatever out there. Yes, I had a rare episode of vasculitis 3 years ago.
