Choosing which service is right for you at a given time may not always be easy – often you have more than one option. Use the checklist below to guide you if you're not sure where to start.
For information about conditions and treatments, read the Health A-Z guides.
Call NHS 111 if you urgently need medical help or advice but it's not a life-threatening situation. You can also call NHS 111 if you're not sure which NHS service you need.
Call 999 if someone is seriously ill or injured and their life is at risk.
Visit a walk-in centre, minor injuries unit or urgent care centre if you have a minor illness or injury (cuts, sprains or rashes) and it can't wait until your GP surgery is open.
Ask your local pharmacist for advice – your pharmacist can give you advice for many common minor illnesses, such as diarrhoea, minor infections, headache, travel advice or sore throats.
