About This Topic


  • Fullness or pressure on the face over a sinus. Pain is usually mild.
  • Sinus pressure occurs above the eyebrow, behind the eye, and under the cheekbone
  • Other common symptoms are a stuffy or blocked nose or nasal discharge.
  • Your child may also have a nasal drip down the back of the throat. This is called a postnasal drip.
  • Also, may have a sore throat and throat clearing from postnasal drip.


  • A doctor can diagnose viral sinusitis by reviewing the details of your symptoms. Tests are not needed.


  • Caused by the many viruses that cause the common cold.
  • A cold infects the lining of the nose. It also infects the lining of all the sinuses.
  • The sinuses normally drain into the nose. If a sinus opening becomes blocked, it can cause pressure.
  • Viral sinusitis is much more common than bacterial sinusitis.

Color of Nasal Discharge with Colds

  • The nasal discharge changes color during different stages of a cold. This is normal.
  • It starts as a clear discharge and later becomes cloudy.
  • Sometimes it becomes yellow or green colored for a few days. This is still normal.
  • Colored discharge is common after sleep, with allergy medicines or with low humidity. (Reason: All of these events decrease the amount of normal nasal secretions.)


  • Cover the nose and mouth with a tissue when coughing or sneezing.
  • Wash hands often. After coughing or sneezing are important times.

After Care Advice

  • Sinus congestion is a normal part of a cold. It should clear up on its own.
  • Usually, nasal washes can prevent a bacterial sinus infection.
  • Antibiotics are not helpful for the sinus congestion that occurs with colds.
  • Here is some care advice that should help.
  • Try to get your child to drink lots of fluids.
  • Goal: Keep your child well hydrated.
  • It also will thin out the mucus discharge from the nose.
  • It also loosens up any phlegm in the lungs. Then it's easier to cough up.
Nasal Saline to Open a Blocked Nose:
  • Use saline (salt water) nose drops or spray to loosen up the dried mucus. If you don't have saline, you can use a few drops of bottled water or clean tap water. Teens can just splash a little tap water in the nose and then blow.
  • STEP 1: Put 3 drops in each nostril.
  • STEP 2: Blow each nostril out while closing off the other nostril. Then, do the other side.
  • STEP 3: Repeat nose drops and blowing until the discharge is clear.
  • How often: Do nasal saline when your child can't breathe through the nose.
  • Saline nose drops or spray can be bought in any drugstore. No prescription is needed.
  • Saline nose drops can also be made at home. Use 1/2 teaspoon (2 ml) of table salt. Stir the salt into 1 cup (8 ounces or 240 ml) of water. You must use bottled or boiled water for this purpose.
  • Reason for nose drops: Blowing alone can't remove dried or sticky mucus.
  • Other option: use a warm shower to loosen mucus. Breathe in the moist air, then blow each nostril.
  • If the air in your home is dry, use a humidifier. Reason: Dry air makes nasal mucus thicker.
Decongestant Nose Spray (No prescription needed):
  • Use this only if the sinus still seems blocked up after nasal washes. Also, only use for age 12 years or older. Use the long-acting type such as Afrin.
  • Dose: 1 spray on each side. Do this 2 times per day.
  • Always clean out the nose before using.
  • Use for 1 day. After that, use only for symptoms.
  • Don't use for more than 3 days. (Reason: Can cause rebound congestion).
  • Oral decongestants (such as Sudafed) are not advised for children.
  • For fevers above 102° F (39° C), give acetaminophen (such as Tylenol) or ibuprofen. Note: Lower fevers are important for fighting infections.
  • For ALL fevers: Keep your child well hydrated. Give lots of cold fluids.
Pain Medicine:
  • To help with the pain, give acetaminophen (such as Tylenol) or ibuprofen. Use as needed.
What to Expect:
  • With this advice, the viral sinus blockage goes away in 7 to 14 days.
  • The main risk is a sinus infection from bacteria. This can occur if bacteria multiply within a blocked sinus. This leads to a fever and increased pain.
  • A bacterial sinus infection will need antibiotics. Once on treatment, the symptoms will improve in a few days.
Return to School:
  • Sinus infections cannot be spread to others.
  • Your child can return to school after the fever is gone.
  • Your child should feel well enough to join in normal activities.
