A sinus infection is known as the inflammation of the sinuses and the nasal passages.
The sinuses are situated within your skull and are lined with mucus membranes.
In case of a viral, fungal, or bacterial infection, autoimmune response, or allergies, these sinuses are inflamed and may lead to headaches and breathing difficulty.
A normal sinus is filled with air, but if an infection occurs, this air is replaced with mucus.
If the mucus is not drained, this may lead to stuffy nose.
In milder cases of sinus infection, natural treatments are available without side effects.
