A sinus infection (sinusitis) is diagnosed by a doctor reviewing your symptoms (facial pain, congestion, discolored mucus, fever) and performing a physical exam, often using a nasal endoscope (a thin tube with a camera) to look inside your nose and sinuses for swelling and blockage. For persistent or severe cases, further tests like CT scans, MRI, or mucus cultures may be used to rule out complications or find the specific cause.
However, if you have some or all of the following symptoms, it is very likely you have a sinus infection:
ANSWER: Allergies and sinus infections often are mistaken for one another. But they are two separate conditions. By paying close attention to the specific symptoms you have, you can usually identify which one is more likely to be causing the problem.
Signs and symptoms
Clogged, inflamed sinuses can block the drainage of the eustachian tube from your ear into your throat. If fluids can't drain from your tubes into your throat, they may build up in your middle ear. The excess fluid causes pressure and also can become infected.
Acute sinusitis usually goes away on its own. Sinusitis is usually caused by a virus , so antibiotics won't help. Over-the-counter medicines and home treatment can help you feel better. Antibiotics do work if sinusitis is caused by bacteria .
To treat a sinus infection while pregnant, focus on safe home remedies like saline nasal rinses, steam inhalation, warm compresses, and staying hydrated, while using acetaminophen for pain and resting; always consult your doctor before taking any medication, especially avoiding NSAIDs (like ibuprofen) and oral decongestants, as some treatments are unsafe during pregnancy.
Sinusitis red flags signal a severe infection needing urgent care, including severe eye symptoms (swelling, redness, vision changes like double vision), high fever, stiff neck, confusion, severe facial swelling/numbness, or neurological changes (difficulty walking/talking), indicating potential spread to the eyes or brain. For less severe cases, seek care if symptoms last over 10 days, worsen after improving ("double sickening"), or include severe facial pain/toothache, suggesting bacterial sinusitis.
Aromatherapy. Aromatherapy is a great home remedy and natural treatment for sinus infections. Using eucalyptus, peppermint or other scents can possibly help open up the respiratory tract. These essential oils can be put into some home humidifiers, or used in a hot shower, which diffuses the scent.
Warning signs you should never ignore
Upper respiratory viral infections and allergy symptoms can mimic sinusitis; however, there are some distinguishing characteristics. Usually we do not diagnose a sinus infection unless symptoms have been present for at least ten days.
Sinus infections and COVID-19 can both cause congestion and sore throats, but COVID-19 often presents with additional symptoms like body aches and loss of smell. Understanding the key differences between COVID and a sinus infection can help with getting an accurate diagnosis and the right treatment.
Sinusitis is common after a cold or flu. The main symptoms of sinusitis include: pain, swelling and tenderness around your cheeks, eyes or forehead.
How is a sinus infection diagnosed? Healthcare providers diagnose sinusitis based on your symptoms and health history. A provider will check your ears, nose and throat for swelling, draining or blockage. They might use an endoscope (a small, lighted instrument) to look inside your nose.
An “acute” sinus infection lasts anywhere from ten days up to eight weeks. A “chronic” infection lasts even longer. It is ongoing — it may seem like it's improving, and then it comes right back as bad as it was at first. Chronic sinus infections may drag on for months at a time.

The first and most important beverage to clear congestion is water. Drinking plenty of water can help thin mucus and ease congestion. Aim for at least eight cups of water a day. If you struggle to drink enough water, try swapping a couple of cups for coconut water or other natural fruit juices.
Other predisposing factors are deviated septum, nasal polyps, cystic fibrosis, dental infections, reflux disease, autoimmune disease, and facial trauma. Notably, primary immunodeficiency is also a factor in developing sinusitis. IgG deficiency, IgA deficiency, and antibody deficiency can all present with sinusitis.
Hay fever or another allergy that affects the sinuses. A common cold that affects the sinuses. A problem inside the nose, such as a deviated nasal septum, nasal polyps or tumors. A medical condition such as cystic fibrosis or an immune system disorder such as HIV/AIDS.
To relieve pregnancy sinus pressure, use safe methods like saline nasal sprays/rinses, steam inhalation, humidifiers, and warm compresses; stay hydrated with water/broth; elevate your head when sleeping; and consider pregnancy-safe OTC nasal sprays (like Rhinocort) or antihistamines (like Chlorpheniramine) after checking with your doctor, who can also recommend what's safe.
You can improve your sinusitis symptoms and sleep better with the following sleep hygiene tips:
The four main symptoms of sinusitis are nasal congestion/blockage, facial pain/pressure, thick, discolored mucus (yellow/green), and a reduced sense of smell or taste, often accompanied by a cough, postnasal drip, and fatigue, making it hard to breathe and causing discomfort around the eyes, cheeks, and forehead.
Sinusitis and earache are closely related as a sinus congestion often develops into an ear congestion. Infected sinuses tend to swell and become congested with mucus, in turn exerting painful pressure on nearby body parts, such as the middle ear. This leads to experiencing severe discomfort in one or both ears.
“COVID-19 causes more of a dry cough, loss of taste and smell, and, typically, more respiratory symptoms,” Melinda said. “Sinusitis causes more discomfort in the face, congestion, nasal drip, and facial pressure.”
