People are urged to think twice before seeking emergency treatment over the bank holiday weekend.
West Norfolk Clinical Commissioning Group is urging people with ailments such as stomach upsets and colds to visit a pharmacy first.
Staff at Lynn’s Queen Elizabeth Hospital treated 700 people at the accident and emergency unit over the Easter holiday.
People with minor injuries or illnesses are advised to treat those at home or at a pharmacy.
Group chairman Dr Ian Mack said all NHS services will be busy during the bank holiday and is advising people to restock their medicine cabinets.
He said: “We’re urging people to think carefully about their illness or injury and whether they really need emergency care.
“If it’s not an emergency, such as a cough, cold, simple stomach upset, minor sprain or cut, consider visiting your local pharmacy or calling 111 for advice.”
