Dustin Lance Black is opening up about a "serious head injury" he recently suffered.

On Monday, the Oscar-winning screenwriter, 48, revealed his health struggles on Instagram and explained that he's been recovering for the past month.

"So I vanished for a while… A month ago I sustained a serious head injury that put me out of commission," Black wrote. "Showing little improvement, my doctors ordered me to shut off my brain in hopes of it healing. This has been a challenging, frightening time for a creative type who depends on what's in his skull to work, care and love. And now I understand the road back will be long."

"But this week my sweet, over the top husband took us to the Greek Islands to make me shut off," he continued, sharing photos of his and husband Tom Daley's vacation. "I can already feel this trip is a step in the right direction, and I finally feel safe sharing a bit again. Thank you for all of your love and patience. More to come. Promise."
