Good to know

Clear vs. Coloured Mucus

Clear: Usually allergies or early viral infection.
Yellow/Green: Indicates immune system is fighting infection (viral or bacterial). It does not automatically mean you need antibiotics.

The "Rebound" Effect

Using decongestant sprays (like Otrivin) for more than 3 days can cause Rhinitis Medicamentosa. Your nose becomes dependent on the spray and gets even more blocked when you stop. Stick to the 3-day rule!

Frequently asked questions

Colds, flu, allergies (hay fever), or cold weather. It's your body flushing out irritants.
