What are the symptoms of a deviated septum?

The most common symptom of a deviated septum is nasal congestion. Symptoms are usually worse on one side, and sometimes occur on the side opposite the bend.  Other symptoms include difficulty breathing, recurrent or repeated sinus infections, frequent nosebleeds, facial pain, headaches, loud breathing, snoring and mild sleep apnea. For some patients, the crooked septum can interfere with the drainage of the sinuses, resulting in repeated sinus infections.
