When 19-year-old Paige arrives at the hospital by ambulance, she's put on a trolley while a resus bed is cleared. She's got the flu but also has type 1 diabetes and has dangerously high sugar levels. She is curled in a ball, pale and shaking.
"There are patients in every cubicle," Consultant Saad Jawaid says, as Paige is wheeled in. "Another ambulance has just rocked up."
We watch as he works with colleagues in the resus unit to find desperately needed bed spaces.
"When beds are full we have to move people - sometimes that means those who can sit are moved out of beds and into chairs," he says.
Paige is given insulin and fluids to try to stabilise her sugar levels. The doctors hope her diabetes will be controlled soon. Getting better from the flu will take longer.
The following day, Paige is in a side room on the acute assessment unit.
"I do struggle a lot in winter," she says. "I was maybe in here two or three weeks ago. Infections and stuff just seem to hit harder than usual."
The number of flu patients in hospital has hit a record high in England for this time of year with NHS leaders warning the country is facing an unprecedented flu season.
At its busiest times, the emergency unit here in Leicester saw more than 1,000 patients a day last winter. On one of the days we were here, 932 patients came through the door. That number is expected to rise in the coming weeks.
Attendance levels are already around 8% higher this year than last year. And the unit faces a daily shortage of between 50 to 70 beds.
At the Royal Infirmary around 64 beds are currently taken up by people with respiratory viruses, including flu.
We meet one patient who waited 106 hours for a bed on a ward. Another, Gary, came in with a stomach bug and finally got a bed after 34 hours.
By late afternoon, the children's waiting area is full. Parents stand rocking crying babies as every seat is taken.
Respiratory cases of flu and bronchiolitis, a condition affecting the lungs of young patients, are rising fast here too.
In just 30 minutes, 30 children arrive at the department.
At five months old this is Oscar's first winter and his first trip to A&E. His mum brought him in because he was wheezing and struggling to breathe. A few hours after arriving, he is finally seen by a doctor and told he has bronchiolitis.
"These bugs are everywhere at the moment - Oscar's older brother brought it home from school and now Oscar has it," says his mum.
Richard Mitchell has been the chief executive of University Hospitals Leicester NHS Trust since 2021 - and has witnessed first-hand how it gets harder to cope with each winter that passes.
"We are already seeing very high levels of flu," he tells us. He expects numbers to climb into January. "That is one of the many things I am concerned about at the moment.
"At this point I feel we are working at the limits of our ability."
The hospital has introduced a new system to manage the flow of patients arriving at its emergency department, as pressure grows on front-line services.
Receptionists, nurses, all the way up to consultants, now sit in a bank of desks at the entrance, assessing patients as they arrive.
This speeds up triage, moving people away from the front door and ensuring those in greatest need receive urgent care.
Staff say the range of cases has become increasingly polarised. Some of the most seriously ill patients are being driven in by relatives because of long waits for ambulances.
Hospital leaders here are trying to take proactive steps - rather than simply reacting to each crisis. But staff and patients alike warn that hospitals across the country are caught in the middle of a system, many believe, is close to breaking point.
In a statement, the Department of Health and Social Care said it was "under no illusions this is going to be a tough winter for our NHS".
A spokesman said: "Flu cases are rising, so it is vital that patients can get protected. Almost 17 million vaccines have been delivered this autumn - 350,000 more compared to this time last year.
"There is no national shortage of the flu vaccine and we would urge everyone eligible to get their vaccination to protect themselves and their loved ones."
