Deviated septum is a condition in which the nasal septum that separates your nostrils is displaced on a side rather than staying on the middle.

The common complications of a septal deviation may include difficulty breathing, snoring, congestion of the nose, etc.

In this article, we’ll discuss the diagnosis of a deviated septum.

The diagnosis is symptomatic and can be done at home all by yourself. However, if you are unable to diagnose a septal deviation in your home, you may consult a doctor to get it done.
