Sinusitis (Sinus Infection)

Sinusitis, or sinus infection, is inflammation of the sinus cavities that causes facial pressure, congestion, headache, and nasal discharge. It can develop after a viral cold or from bacterial overgrowth when mucus builds up and airways become blocked.

At The Medical Group of New Jersey, our urgent-care specialists provide same-day evaluation, imaging when needed, and evidence-based treatment to relieve pain, restore drainage, and prevent recurrence.


Symptom Onset & Initial Evaluation

Sinusitis symptoms often start after a cold or allergy flare-up and may persist for days or even weeks. Typical signs include:

  • Facial pain, pressure, or tenderness (around eyes, cheeks, or forehead)
  • Nasal congestion or thick nasal discharge (yellow or green)
  • Decreased sense of smell or taste
  • Headache or tooth pain
  • Postnasal drip, cough, or fatigue

During your visit, your provider at The Medical Group of New Jersey Urgent Care will review your symptom timeline, prior infections, and allergy history and perform a focused nasal and sinus exam to check for swelling, drainage, or tenderness.


Diagnosis

Diagnosis is primarily clinical, based on your symptoms and exam findings. In certain cases, your provider may order:

  • Nasal endoscopy: To directly visualize inflammation, blockage, or nasal polyps.
  • CT scan of the sinuses: Used for chronic or recurrent sinusitis to detect structural issues.
  • Allergy testing: Identifies environmental triggers such as pollen, dust mites, or mold that may lead to repeated inflammation.

This comprehensive approach distinguishes viral sinusitis (usually resolves without antibiotics) from bacterial sinusitis, which may require targeted treatment.


Treatment & Ongoing Management

Management focuses on reducing inflammation, improving drainage, and relieving pressure.

  • Supportive care: Saline nasal rinses, humidifiers, and adequate hydration keep mucus thin and promote healing.
  • Medications: Nasal corticosteroid sprays reduce swelling inside nasal passages. Decongestants (used short-term) relieve congestion and pressure. Pain relievers like ibuprofen or acetaminophen ease discomfort.
  • Antibiotics: Prescribed only when bacterial infection is strongly suspected or symptoms persist >10 days or worsen after initial improvement.
  • Allergy management: Allergy immunotherapy or antihistamines may be recommended if allergies are a recurring trigger.

Your provider will explain warning signs such as severe headache, facial swelling, or high fever that require urgent reassessment.


Long-Term Outlook

Most cases of acute sinusitis resolve within 7–14 days with proper care. For chronic or recurrent sinusitis, continued allergy control, nasal hygiene, and follow-up visits can significantly reduce flare-ups and improve quality of life.

At The Medical Group of New Jersey, our urgent-care and allergy specialists collaborate to provide comprehensive sinus care—from same-day treatment to long-term prevention—so you can breathe comfortably year-round.
