When to seek immediate medical help

• Chest pain or pressure that does not go away, or chest discomfort with breathlessness, sweating or pain spreading to the arm, jaw, back or neck.
• Sudden face drooping, arm weakness, speech difficulty (stroke signs) or new weakness on one side — even if the symptoms have stopped.
• Severe difficulty breathing, gasping, choking, or being unable to speak normally because of breathlessness.
• Sudden swelling of the lips, tongue or throat, especially with trouble breathing or swallowing.
• A headache that comes on suddenly and is extremely painful.
• Collapse or unconsciousness, a first seizure or a seizure that does not stop, major uncontrolled bleeding or serious injury.
• Sudden confusion or difficulty responding, particularly when someone is severely unwell or has signs of infection.
• Blue, pale or blotchy skin, lips or tongue, or a rash that does not fade when pressed — particularly if someone is unwell.
• Immediate danger of serious self-harm, overdose, or being unable to keep yourself or another person safe.

These are examples, not a complete list. Serious illness may occur without any of these signs. This tool cannot confirm that it is safe to wait.
