Is any of this happening now?
Call 911
Seek urgent or emergency care for sudden shortness of breath, chest pain, coughing up blood, or a painful and swollen leg, as these can be signs of a blood clot.
Severe abdominal pain with persistent vomiting, marked swelling, or an inability to pass stool or gas also needs emergency assessment because it may indicate a blocked bowel.
Other emergency signs, for anyone
Someone who is struggling to breathe, gasping, choking, or cannot get words out
Someone who has chest pain, tightness or pressure lasting more than a few minutes
Someone who has sudden weakness or drooping on one side of the face or body, slurred speech, or sudden confusion
Someone who is unconscious, or cannot be woken
Someone who is bleeding heavily and it will not stop with firm pressure
Someone who has had a seizure that will not stop, or does not wake up afterwards
Someone who has lips or skin that look pale, blue, grey or blotchy
