Pus Discharge from the Nose: Causes, Symptoms, and Treatment

What is Pus Discharge from the Nose?

Pus discharge from the nose, also known as purulent nasal discharge, occurs when the nasal passages become infected, often due to bacterial sinusitis or other upper respiratory infections. The discharge is typically thick, yellow or green in color, and is a result of the body's immune response to infection. This type of discharge can be accompanied by other symptoms like nasal congestion, facial pain, and a reduced sense of smell.

Causes of Pus Discharge from the Nose

• Bacterial Sinusitis. The most common cause of pus discharge from the nose is bacterial sinusitis, where bacteria infect the sinuses and cause inflammation, leading to thick, pus-filled mucus.
• Viral Infections. While viral infections like the common cold typically cause clear nasal discharge, they can sometimes lead to secondary bacterial infections, which result in pus-like discharge.
• Allergic Rhinitis. In some cases, allergies can lead to sinus infections that cause pus discharge, although this is less common.
• Foreign Objects. A foreign object stuck in the nasal cavity, especially in children, can lead to infection and pus-like discharge.
• Nasal Polyps. Noncancerous growths in the nasal passages can cause sinus infections, leading to pus discharge along with other symptoms like congestion and difficulty breathing.

Symptoms of Pus Discharge from the Nose

• Thick, Yellow or Greenish Discharge. The main symptom is thick, pus-filled nasal discharge, which may be accompanied by a foul odor.
• Nasal Congestion. Blocked nasal passages can make it difficult to breathe through the nose.
• Facial Pain or Pressure. Pain in the face, particularly around the eyes, forehead, or cheeks, may be present, especially in cases of sinus infection.
• Headache. Sinus infections often cause headaches due to pressure in the sinus cavities.
• Loss of Smell. A reduced or lost sense of smell is common when the nasal passages are blocked or infected.

Treatment for Pus Discharge from the Nose

• Antibiotics. If a bacterial infection is the cause of the pus discharge, antibiotics may be prescribed to treat the infection.
• Decongestants. Medications that reduce nasal congestion, such as nasal sprays or oral decongestants, can help relieve symptoms.
• Saline Nasal Rinses. Rinsing the nasal passages with a saline solution can help clear out mucus and pus, promoting healing.
• Warm Compresses. Applying a warm compress to the face can help relieve sinus pressure and pain associated with the infection.
• Antihistamines. If allergies are contributing to the symptoms, antihistamines may help reduce inflammation and mucus production.
