The NHS website gives advice about what to do when you have an urgent medical need, by offering the opportunity to complete a 111 online triage. Using 111 online, you are asked a series of questions about your symptoms and then receive advice about the best place to get further help.
If you need to speak to a nurse or a doctor, 111 online will advise which service you need and may be able to arrange for them to call you. If your answers cannot rule out a more serious condition, you will be advised to ring 999 for further assistance and an ambulance may be dispatched, if required.
