Sinusitis vs. Allergic Rhinitis vs. Colds: Symptoms, Home Care & When to See an ENT Doctor

A stuffy nose that won't go away is one of the most common reasons Filipinos visit a doctor. Rainy season viruses, dust, smog, and air-conditioned offices all play a part. But a blocked nose can come from three very different problems: a common cold, sinusitis, or allergic rhinitis. Knowing which one you have helps you choose the right care and avoid unnecessary antibiotics.

Cold, Sinusitis, or Allergy? How to Tell the Difference

	Common cold	Sinusitis	Allergic rhinitis
Typical duration	7–10 days	Over 10 days, or gets worse after first improving	As long as you are exposed to the trigger; can last for weeks or all year
Nasal discharge	Clear, may thicken	Thick, yellow-green, may drip down the throat	Clear and watery
Face pain or pressure	Mild, if any	Common: cheeks, forehead, around the eyes, worse when bending forward	Uncommon
Itchy nose and eyes, sneezing fits	Some sneezing	Uncommon	Very common
Fever	Sometimes, low	Sometimes	No

Sinusitis

Your sinuses are air-filled spaces in the bones of your face. In sinusitis, their lining becomes swollen and mucus cannot drain properly. Typical symptoms are:

• Blocked nose and thick nasal discharge
• Pain, pressure, or fullness in the face
• Reduced sense of smell
• Post-nasal drip and cough, often worse at night
• Headache, bad breath, or tooth pain in the upper jaw

Most sinusitis starts with a cold and is caused by a virus, so antibiotics do not help and it gets better on its own. A doctor may consider a bacterial infection if:

• Symptoms last more than 10 days without improving
• You start to get better, then suddenly get worse again
• You have a high fever with thick nasal discharge and facial pain for several days

Sinusitis that lasts 12 weeks or longer is called chronic sinusitis. It may be linked to allergies, nasal polyps, a deviated septum, or other problems that an ENT doctor can assess.

Allergic Rhinitis

Allergic rhinitis happens when your immune system overreacts to something harmless in the air. It often runs in families and frequently comes with asthma or eczema. Common triggers in the Philippines include:

• House dust mites in mattresses, pillows, stuffed toys, and carpets, the most common trigger
• Mold, especially during the rainy season and in humid rooms
• Cockroaches
• Pet dander from cats and dogs
• Smoke, strong smells, and air pollution, which irritate the nose further

Typical signs are bursts of sneezing, a runny and itchy nose, itchy or watery eyes, and symptoms that come back in the same places or seasons. If you also wheeze or feel tightness in your chest, read our guide on asthma and allergies.

What Helps at Home

• Saline nasal rinse or spray: rinses out mucus and allergens. Use sterile, distilled, or boiled-then-cooled water, never plain tap water.
• Rest and fluids for colds and viral sinusitis
• Steam (suob) can loosen mucus, but be very careful with hot water, especially around children, because burns are common
• Reduce dust mites: wash bedsheets and pillowcases in hot water weekly, sun-dry pillows, and keep stuffed toys out of the bed
• Keep air-conditioners and electric fans clean and fix leaks that cause mold
• Avoid smoke, including second-hand smoke

Ask a doctor or pharmacist before using medicines. Antihistamines and steroid nasal sprays can help allergic rhinitis. Decongestant nasal sprays should not be used for more than about three days, because longer use can make the blockage worse once you stop. Don't take antibiotics without a prescription.

Warning Signs: See a Doctor Urgently

Sinus infections can rarely spread to the eyes or brain. Go to the emergency room or see a doctor the same day if you have:

• Swelling, redness, or pain around one eye
• Double vision, blurred vision, or difficulty moving the eye
• A severe headache, stiff neck, or confusion
• High fever that does not go down
• Swelling of the forehead

Ear Infections in Children

Colds and allergies in children often lead to middle ear infections. Signs include ear pain, tugging at the ear, fever, crying at night, or not hearing well. See a pediatrician if your child has these symptoms. If there is fluid or pus coming out of the ear, or hearing problems that last, an ENT doctor should check it.

When to See an ENT Doctor

An ENT doctor (otolaryngologist) specializes in the ear, nose, and throat. Consider seeing one if:

• Your nose is blocked for more than 12 weeks, or sinusitis keeps coming back several times a year
• Medicines prescribed by your general doctor are not helping
• You have lost your sense of smell for a long time
• You have frequent nosebleeds, or a blocked nose on one side only
• You snore loudly or have trouble breathing through your nose at night
• You have ear discharge, hearing loss, or a lump in the neck

The ENT doctor may look inside your nose with a thin camera (nasal endoscopy) and may order a CT scan of the sinuses. Most people improve with medicines and nasal care. For chronic cases that don't improve, minimally invasive sinus surgery may be an option. For allergic rhinitis, allergy testing can identify your triggers.
