The Orange Is The New Black star took to her Instagram to reveal she was suffering an allergic reaction.
The 31-year-old posted an image of herself slumped over a toilet, revealing she had an adverse reaction to the Codeine prescribed to her for her back pain.
Despite the serious situation, Rose saw the humour in the situation, captioning the photo: 'Ever found out you’re allergic to Codine (sic) in an entirely pink room... with pink walls, pink stairs, pink doors, all while you’re 4 hours from home neither... but that would really suck.'
The Pitch Perfect 3 star also revealed this week that she had undergone a spinal surgery.
Rose shared a series of 'progress' snaps to social media on Monday while recuperating from the operation.
'So... for the past few years (decade) I’ve been dealing with a spine issue,' Ruby tweeted to her 1.34 million Twitter followers.
'I am now recovering from a back procedure, but I do need to stay active, so before I get seen with my cane and wheelchair in public, I’d rather put it out there that I’m fine and going to be fine.'
We're wishing Rose a speedy recovery!
