Call 999 in an emergency.
A medical emergency is a situation in which the health of a person is at high risk of deteriorating rapidly without immediate medical attention.
For example, chest pains, increasing difficulty in breathing, impaired consciousness and any of the signs of a stroke (facial weakness, inability to lift a limb or slurred speech) constitute an emergency.
In a medical emergency, you can access urgent paramedical help by calling 999. If you need medical help now, use NHS 111 online (111.nhs.uk) or call 111.
In non-emergency:
Call 111 when it's a concern, but less urgent than 999.
