Actor Mark Ruffalo (aka The Hulk) has posted on social media about having personal experience with “brutal, persistent” Lyme disease.

He shared his comment on Facebook, Twitter and in an Instagram story.

Ruffalo was encouraging people to watch the Lyme documentary The Quiet Epidemic, now available to stream on AppleTV/iTunes, Amazon Prime Video, and Vimeo on Demand.

He called The Quiet Epidemic “a powerful and award-winning expose about the hidden epidemic of Lyme disease and our for-profit healthcare system.”

He added, “From personal experience, Lyme disease can be brutal, persistent, and misdiagnosed. The healthcare industry is way behind on this disease.”

Pop Sugar quickly picked up the story. The lifestyle website featured Ruffalo (and his endorsement of The Quiet Epidemic) in a list of celebrities who have spoken publicly about their experiences with Lyme disease.

The filmmakers of The Quiet Epidemic said, “We are honored to have his support and hope more celebrities leverage their platform for good, whether for Lyme disease or other important causes.”
