Do Sinus Infections Go Away On Their Own? It Depends On The Cause.

Many people suffer from seasonal sinus infections that seemingly come out of nowhere. However, treating it can be an issue because the symptoms are so similar to that of a cold or the flu. The numerous differing claims made by friends or family may not help either: some may say it takes specialized treatment, while some say not to worry. But do sinus infections go away on their own?

In this post, we’ll be looking at some of the basic symptoms of a sinus infection. Next, we’ll look at whether a sinus infection can go away by itself.

How Sinus Infections Work

Your sinuses are hollow organs that reside inside the structure of your face. There are large sinuses behind your cheekbones and in your forehead. Their function is to moisten the air and produce mucus, which traps allergens, pollen, and dust. Therefore, you’re able to breathe clean air and keep your lungs free of pollutants.

So, because they’re hollow, the sinuses are normally filled only with air and lined with a thin layer of mucus. But when you have sinusitis, they become infected and fill with fluid.
Sinus infections have some distinctive symptoms, such as:

  • Fever
  • A runny nose
  • Postnasal drip
  • Nasal blockage
  • Congestion
  • Puffy skin around the cheeks
  • A feeling of pressure or fullness around the face

Do Sinus Infections Go Away On Their Own?

Whether a sinus infection can go away by itself depends on why it happened in the first place.

A sinus infection caused by bacteria may not necessarily disappear on its own. Sometimes, a doctor may prescribe you antibiotics, which you would take for around two weeks. After you start taking the medication, your symptoms will likely go away.

If the sinus infection is due to a fungus, you may be prescribed an antifungal medicine or fungicide.

Remember, however, that the most common form of sinusitis is viral. In this case, though, you will likely not need any treatment as the infection will resolve on its own within about two weeks. You can help the process along by:

  • Using a saline spray to rinse your nasal passages. This allows the mucus to thin out and acts as a decongestant, letting you breathe easier.
  • Using a nasal decongestant. For particularly bad cases where your sinus infection interferes with your daily routine, you can temporarily use an over-the-counter nasal decongestant, although not as frequently as a saline rinse.
  • Staying hydrated. Drinking more water can lessen the viscosity of mucus, making it thinner and easier to drain out of your nasal passages.
  • Getting enough rest. The tiredness that comes with a sinus infection is your body trying to fight it. Allow your body to get the rest that it needs to recover.


Whenever you’re ill, always follow the best practices of maintaining your hygiene, getting enough rest and sleep, and staying hydrated. Allowing your body the best chance at fighting off infection increases your chances of healing quickly. And of course, if you have any questions, don’t hesitate to contact your doctor.
