Common Sinus Infection Symptoms
Sinus symptoms often start like a cold, but can feel more intense, especially in the face and head.
Common sinus infection symptoms we see include:
- Stuffy or blocked nose
- Thick yellow or green nasal drainage
- Facial pressure or pain (forehead, cheeks, or around the eyes)
- Headache
- Post-nasal drip (mucus draining into the throat)
- Sore throat or cough (often worse at night)
- Bad breath
- Fever
- Fatigue
- Ear pressure or fullness
Many sinus infections improve with time and supportive care. Consider urgent care if your symptoms are lingering, getting worse, or disrupting your routine.
What Causes a Sinus Infection?
A sinus infection (sinusitis) happens when the lining of the sinuses becomes inflamed. Several factors can trigger this inflammation, ranging from common colds to environmental exposures.
Viral Illness
Most sinus infections begin with a viral illness, such as the common cold. When a virus causes swelling in the nasal passages, it can block normal sinus drainage. This trapped mucus creates pressure and discomfort. Viral sinus infections often improve on their own but may cause congestion, facial pain, and thick nasal discharge.
Bacterial Infection
In some cases, a sinus infection develops after a viral illness when bacteria grow in trapped mucus. Bacterial sinus infections may cause more persistent symptoms, including facial pressure, headaches, nasal congestion, and discolored discharge that lasts longer than 10 days or worsens after initial improvement. Medical evaluation can help determine the appropriate treatment.
Allergies and Irritants
Seasonal allergies, dust, smoke, and other airborne irritants can inflame the nasal passages and sinuses. Ongoing inflammation may block normal mucus drainage, increasing the likelihood of infection. People with allergic rhinitis, or hay fever, may experience recurring sinus symptoms during certain times of the year or with specific environmental triggers.
Structural Factors
Physical differences inside the nose can affect sinus drainage. A deviated septum, nasal polyps (noncancerous growths), or narrowed sinus passages may make it harder for mucus to flow normally. When drainage is restricted, bacteria or viruses are more likely to multiply, increasing the risk of repeated or chronic sinus infections.
How We Evaluate Sinus Infection Symptoms
Your visit starts with a focused review of your symptoms and a physical exam.
Your provider may ask:
- How long your symptoms have been present
- Whether symptoms are improving or worsening
- If you have allergies, asthma, or frequent sinus issues
- What medications or home care you’ve already tried
Based on your history and exam, we’ll explain what may be causing your symptoms and outline a care plan that fits your needs.
Sinus Infection Treatment Options
Treatment depends on the likely cause of your symptoms and how severe they are. Your provider may recommend options that help reduce swelling, relieve pressure, and support recovery.
Possible treatment options may include:
- Symptom relief medications (such as decongestants or nasal sprays when appropriate)
- Allergy support if allergies may be the cause
- Prescription medication if your provider believes it’s needed
- Home care guidance to help you stay comfortable
If your provider suspects a bacterial infection, they may recommend an antibiotic. If not, they may recommend supportive care and symptom relief. Either way, you’ll leave your visit with clear next steps.
