Sinus Infection: Symptoms, Home Care, Antibiotics, and When to Get Medical Care

Sinus Infection (Sinusitis)

Sinusitis, often called a sinus infection, happens when the lining of the sinuses becomes inflamed or swollen. This can lead to mucus buildup, pressure, congestion, facial discomfort, and drainage. Sinus symptoms often happen after a cold, allergies, or another upper respiratory infection.

Most sinus infections are caused by viruses and improve without antibiotics. However, some sinus infections can become bacterial or more severe, and medical care may be needed.

Common Sinus Infection Symptoms

Sinusitis may cause:

• Stuffy or congested nose

• Runny nose

• Thick yellow or green nasal drainage

• Postnasal drip

• Facial pressure or pain

• Pressure around the cheeks, forehead, or eyes

• Headache

• Tooth pain, especially upper teeth

• Cough, often worse at night

• Bad breath

• Fatigue

• Reduced sense of smell or taste

• Ear pressure or fullness

Symptoms can feel similar to a cold, allergies, COVID, or the flu, so timing and severity matter.

Is It Viral, Allergies, or Bacterial Sinusitis?

Many sinus symptoms are viral and improve with supportive care. Antibiotics do not work against viruses.

A bacterial sinus infection is more likely when symptoms are severe, last longer than expected, or worsen after initially improving. Acute bacterial rhinosinusitis may be diagnosed when symptoms are severe for more than 3–4 days, persistent for more than 10 days without improvement, or worsening after initial improvement.

You should consider medical care if symptoms last more than 10 days, worsen after improving, include fever for more than 3–4 days, or include severe headache or facial pain.

Are Antibiotics Always Needed?

No. Most sinus infections do not need antibiotics. Some bacterial sinus infections may also improve without antibiotics, depending on severity and patient risk factors.

When antibiotics are appropriate for acute bacterial sinusitis, clinical guidelines support amoxicillin with or without clavulanate as a common first-line option for most adults.

The best treatment depends on your symptoms, duration, allergies, medical history, pregnancy status, prior antibiotic use, and risk for complications.

When to Seek Medical Care

You should schedule medical care if:

• Symptoms last more than 10 days without improving

• Symptoms worsen after initially improving

• You have fever for more than 3–4 days

• You have severe facial pain or severe headache

• You have repeated sinus infections

• You have chronic sinus symptoms

• You have asthma, COPD, immune system problems, or other higher-risk conditions

• You are unsure whether symptoms are allergies, a cold, COVID, flu, dental infection, migraine, or sinusitis

• You need guidance on safe over-the-counter medication options

When to Go to Urgent Care or the ER

Seek urgent in-person care right away if you have:

• Swelling or redness around the eyes

• Vision changes or double vision

• Severe headache

• Stiff neck

• Confusion

• Forehead swelling

• Severe facial swelling

• High or persistent fever

• Severe symptoms that are rapidly worsening

• Shortness of breath, chest pain, fainting, or severe weakness

Fever, swelling or redness around the eyes, severe headache, forehead swelling, confusion, double vision or other vision changes, and stiff neck as symptoms that may signal a serious infection and need prompt evaluation.

Can Telehealth Help With Sinusitis?

Yes, telehealth may be appropriate for many adults with mild to moderate sinus symptoms. During a virtual visit, your provider may ask about:

• How long symptoms have been present

• Whether symptoms are improving, worsening, or recurring

• Fever and temperature

• Facial pain or pressure

• Nasal drainage and congestion

• Cough, sore throat, ear pain, or headache

• Allergy history

• Asthma or lung disease

• Medication allergies

• Recent antibiotic use

• Pregnancy possibility

• COVID, flu, or other respiratory illness exposure

• Red flag symptoms that require in-person care

Telehealth may not be appropriate if symptoms suggest a serious infection, eye involvement, severe swelling, neurological symptoms, severe shortness of breath, chest pain, or another condition that needs a hands-on exam.

How to Help Prevent Sinus Problems

You may reduce sinus irritation and infection risk by:

• Washing your hands regularly

• Avoiding close contact with people who are sick when possible

• Managing allergies

• Avoiding smoke and vaping

• Staying hydrated

• Using a humidifier if indoor air is dry

• Keeping nasal passages moist with saline spray when needed

• Staying current with recommended vaccines

• Cleaning humidifiers regularly to prevent mold or bacteria buildup
