More than 800 people needed medical help on the first day of this year's V Festival at Weston Park.
A total of 828 festival goers were attended to by West Midlands Ambulance Service, Venture Event Medical Management and St John Ambulance Service at the site yesterday.
Ambulance crews took 15 people to hospital for a range of conditions including fall injuries and pre-existing medical problems.
Nearly 300 staff and volunteers are providing medical help at the festival.
A West Midlands Ambulance Service spokesman said: “Doctors, nurses, paramedics, technicians, managers, first aiders, control room staff and logistics staff are on hand to make sure that if you are unfortunate enough to fall ill, help won’t be far away.
"In most cases, a trip to hospital isn’t required and after treatment revellers are able to continue enjoying the event.
"So far, the majority of the patients have been treated for medical issues, many already had pre-existing medical conditions but crews have also seen a large number of alcohol related cases."
