If you make it through this severe flu season without getting sick, congratulations. But perhaps a loved one is not as lucky and temporary caregiving duties have fallen on your shoulders.

Most people recover from the flu at home with some tender loving care and by following doctor's orders for medications and treatment. But experts at flu.gov advise getting immediate medical care for your loved one if you see any of the following signs:

Difficulty breathing or shortness of breath

Purple or blue discoloration of the lips

Pain or pressure in the chest or abdomen

Sudden dizziness or confusion

Severe or persistent vomiting

Another warning sign that the patient may need medical care is if flu symptoms improve but then quickly return, accompanied by a fever and a cough that's worse than before.
