Now, she has taken to Instagram to share a photo from her hospital bed with a lengthy caption that explains part of what went down.

Miller's doctor recently addressed the star's condition in an interview with PEOPLE.
“It was not an infection, it was a type of a non-Hodgkin’s lymphoma – it’s a type of a cancer,” said Dr. Hooman M. Melamed, an orthopedic spine surgeon at Cedar Sinai Marina Del Rey Hospital.
Dr. Hooman M. Melamed revealed that Miller will most likely undergo chemotherapy or radiation.
“We’re getting an oncologist involved and we have to figure out what the next steps are as far as chemotherapy or radiation or more spine surgery. Depending on the tumour type, depending on the sensitivity of the tumour – it just depends the type but I feel more than yes, she will undergo chemotherapy or radiation.”
Doctors are not sure exactly where the rumour has spread from, or if it will continue to spread.
“There’s a chance this can spread to any part of the body … this is probably coming from somewhere else,” he says. “We don’t know where the source is. Any tumour that spreads anywhere is automatically Stage 4, but we have not determined the stage yet.”
Miller recently served a 366-day prison sentence for committing bankruptcy fraud.
Our hearts go out to the former reality star at this difficult time.
