Holby City favourite Rosie Marcel was rushed into hospital for emergency surgery this week.
The Jac Naylor star is now resting up at home, and thanked the NHS via Instagram with some warm words.
"Ended up at the old emergency room the other night," she wrote. "Stoke Mandeville is my new local ish hospital and they were brilliant. Ambulance crew were amazing too.
"Had surgery the next day and home soon after that."

Marcel and the rest of the Holby gang are no longer a part of our lives after the BBC One medical soap was cancelled last year.
Paying tribute to the show after wrapping forever as Jac Naylor, the actress wrote back in December: "I have loved playing Jac Naylor. I have loved being here for 16 years.
"Thank you everyone @bbcholbycity and thank you all the beautiful fans and friends of the show. Xxxxx."
