Nasal congestion and discharge are extremely common problems that commonly occur together but occasionally occur alone.

Less common causes include
Fluid sometimes drains from an infected sinus.
Children sometimes put a foreign object in their nose. If adults do not see them do this, the first sign may be a foul-smelling nasal discharge due to infection and irritation from the foreign object. Rarely, adults with mental disorders put objects in their nose.
People who use nasal decongestant sprays for more than 3 to 5 days often experience significant rebound congestion (the return of congestion that is worse than before) when the effects of the drug wear off. People then continue using the decongestant in a vicious circle of persistent, worsening congestion. This situation (rhinitis medicamentosa) may persist for some time, and people may misinterpret it as a continuation of the original problem rather than a consequence of treatment.
People with vasomotor rhinitis have a recurrent watery nasal discharge that occurs without any known triggers.
Not all episodes of nasal congestion and discharge require immediate evaluation by a doctor. The following information can help people decide whether a doctor’s evaluation is needed and help them know what to expect during the evaluation.

People who have nasal congestion and discharge but no warning signs should call their doctor. They may not need to be seen, particularly if they have typical cold symptoms and are otherwise healthy.
Doctors first ask questions about the person's symptoms and medical history and then do a physical examination.

During the medical history, doctors ask about the following:
The nature of the discharge (such as whether it is watery, sticky, pus-filled, or bloody) and whether it is present most or all of the time (chronic) or comes and goes
Symptoms of possible causes, including fever and face pain (sinusitis); watery, itchy eyes (allergies); and sore throat, a general feeling of illness (malaise), fever, and cough (viral upper respiratory infection)
Whether people have allergies, diabetes, or a weakened immune system and whether they have been using decongestant sprays
If the discharge comes and goes, doctors try to determine whether it relates to where the person lives, the season, or exposure to potential triggers (such as pets or dust).
During the physical examination, doctors look at the following:
The face for redness over the sinuses just above the eyebrows (frontal sinuses) and the sinuses in the cheekbones (maxillary sinuses)
The membranes lining the nose (nasal mucosa) for color (whether they are red or pale), swelling, color and nature of the discharge, and (particularly in children) whether there is any foreign object
Doctors also tap their finger over the sinuses to look for tenderness.
Testing is generally not needed for acute nasal symptoms unless severe sinusitis is suspected in a person with diabetes or a weakened immune system or for those with symptoms that do not resolve with treatment. These people usually should have a computed tomography Computed Tomography (CT) In computed tomography (CT), which used to be called computed axial tomography (CAT), an x-ray source and x-ray detector rotate around a person.

The best way to treat nasal congestion and discharge is to treat the underlying disorder. There are two basic approaches to relieving the symptoms:
Decongestant sprays typically contain oxymetazoline. Decongestants taken by mouth include pseudoephedrine. Decongestant sprays should not be used for more than a day or 2 to avoid the problem of rebound congestion.
Antihistamines can be taken for symptoms due to viral infection and allergic reactions. Doctors often recommend diphenhydramine for people with colds. For people with allergies, other antihistamines that have fewer side effects, such as fexofenadine, are used. Nasal corticosteroid sprays (such as mometasone) also help allergic conditions.
Decongestants and antihistamines are not recommended for children under 6 years of age.
Antihistamines can have sedating and anticholinergic effects (such as confusion, blurred vision, and loss of bladder control). These effects are more common among and more troublesome in older people. Antihistamines should be avoided or used in decreased dosages. Pseudoephedrine, a decongestant, stimulates the heart rate and increases blood pressure. If pseudoephedrine is needed, it should be taken at the lowest effective dose.
