Online Sinus Infection Treatment

Sinus infections—more accurately called sinusitis—can make day-to-day life miserable. Sinusitis happens when the lining of the sinuses becomes inflamed and can be caused by viruses, allergies, or (less commonly) bacteria or fungi. Most cases are viral and improve without antibiotics, but some infections can worsen or lead to complications if they aren’t managed appropriately.

Sinusitis is common in both adults and children. Knowing the symptoms, when to suspect a bacterial infection, and when to seek medical care can help you recover faster and avoid unnecessary medications.
