Call your health care provider if:

• You have a high fever.
• What comes from your nose is yellow and green. Your face hurts or you have fever. This may be a sign of a bacterial infection.

Self-care

Until you see your health care provider, try these simple steps to relieve symptoms:

• Avoid anything you know you're allergic to.
• Try an allergy medicine you can get without a prescription. If you're also sneezing and your eyes are itching or watering, you might have allergies. Be sure to follow the label instructions exactly.
• For babies, put several saline drops into one nostril. Then gently suction that nostril with a soft rubber-bulb syringe.

To relieve saliva that builds up at the back of the throat, also known as postnasal drip, try these measures:

• Avoid common irritants such as cigarette smoke and sudden humidity changes
• Drink plenty of water.
• Use nasal saline sprays or rinses.
