Dan Aykroyd was rushed to the hospital over the weekend after complaints of stomach pain, but he has since been released and is recovering at home.
TMZ is reporting the "Ghostbusters" star was feeling ill the morning of June 4 and paramedics had to respond to his home. He was transported via ambulance to a Los Angeles-area hospital.
Doctors ran tests on the legendary actor but are still unclear about the cause of the pain.
He has not addressed his emergency room visit on social media, where he has become somewhat active while promoting the new "Ghostbusters" remake that he is a part of.
Dan's health has often been a cause of concern. In 2013, he revealed that he has Asperger's syndrome.
"It wasn't diagnosed until the early Eighties when my wife persuaded me to see a doctor," he told the Daily Mail. "One of my symptoms included my obsession with ghosts and law enforcement — I carry around a police badge with me, for example. I became obsessed by Hans Holzer, the greatest ghost hunter ever. That's when the idea of my film Ghostbusters was born."
He said he is able to manage his Asperger's.
