What Causes Sinus Infections?

Sinus infections (also known as acute or chronic sinusitis) are caused by swelling and inflammation in the sinus cavity. A sinus infection may start out as a basic cold, with similar symptoms including nasal congestion, itching, and a runny nose. Acute sinusitis is sinus infectionusually triggered by a common cold or seasonal allergies, and may be treated with over the counter medication like antihistamines and decongestants, or resolve on its own. Chronic sinusitis can last as long as eight weeks, and often results from an infection, or growths in the nasal passage, and may require prescription medication and medical treatment.

It can be difficult to distinguish between a cold and a sinus infection in the early stages, but the most common signs of a full blown sinus infection are:

  • headache
  • facial pain (ear, forehead, back of eyes)
  • runny nose
  • nasal congestion
  • fever
  • fatigue
  • tenderness and swelling around the nose and eyes
  • temporary loss of smell
  • phlegm
  • throat irritation
