How can i tell the difference between a sinus infection, and just seasonal fall allergies? sinus infection vs. allergies

A doctor has provided 1 answer

Difference: The mucus discharge in allergies is clear and watery. The nasal discharge in a paranasal sinusitis is thick, green or yellowish and is rarely bloody. Headache is more common in sinusitis which often follows a prolonged head cold.
