What Causes a Runny Nose?

At Reliable MD, we understand that a runny nose—medically known as rhinorrhea—can be both bothersome and disruptive to your daily life.

The most common causes of a runny nose include:

• Common Cold – Viral infections that lead to inflammation in the nasal passages and excess mucus production.

• Allergies – Reactions to allergens like pollen, dust, mold, or pet dander can trigger nasal congestion and a runny nose.

• Sinus Infection (Sinusitis) – Inflammation or infection of the sinuses can cause mucus to drain from the nasal passages, resulting in a runny nose.

• Flu – Like the common cold, the flu virus can cause a runny nose along with other symptoms like fever, fatigue, and body aches.

• Environmental Irritants – Exposure to smoke, strong odors, pollution, or chemicals can irritate the nasal passages, leading to a runny nose.

• Dry Air – Dry conditions can cause the mucous membranes in the nose to become irritated, leading to a runny nose as the body attempts to compensate.

• Medication Side Effects – Some medications, especially nasal decongestant sprays when overused, can cause a rebound effect, leading to a runny nose.

• Pregnancy – Hormonal changes during pregnancy can lead to a condition called “pregnancy rhinitis,” which includes a runny nose.

• Cold Weather – Cold air can irritate the nasal passages, resulting in increased mucus production and a runny nose.

While most cases of a runny nose are mild and resolve on their own, persistent, severe, or unexplained symptoms may require further evaluation. At Reliable MD, our experienced healthcare providers are here to help identify the underlying cause of your symptoms and recommend the most effective treatment options.

At Reliable MD, we know that a runny nose isn’t always just a sign of the common cold. While colds are a frequent culprit, many other conditions can cause a runny nose (medically known as rhinorrhea). Allergies—including hay fever—are a common non-infectious cause, often triggered by pollen, dust, or pet dander and producing clear, watery discharge. Environmental factors such as cold air, spicy foods, or exposure to irritants like smoke or strong odors can also lead to increased nasal secretions.

Other possible causes include sinus infections (sinusitis), the flu, or even crying. In some cases, medications or hormonal changes—such as those experienced during pregnancy—may be responsible. Because a runny nose may be caused by a range of factors, it’s important to look for other symptoms. If your runny nose is persistent, severe, or accompanied by unusual symptoms (such as high fever, facial pain, or thick, discolored mucus), it could be a sign of something more than a simple cold.

Our team at Reliable MD is here to help you determine the underlying cause of your symptoms and recommend the right treatment. We are committed to providing thorough, compassionate care to help you feel your best.

A runny nose is a common symptom, often caused by colds, allergies, or changes in the weather, and typically resolves on its own. However, at Reliable MD, your health and peace of mind are our top priorities.

You should see a doctor for a runny nose if:

• The symptoms persist for more than 10 days without improvement.

• You experience severe facial pain or pressure, which may indicate a sinus infection.

• You have a high fever (above 101°F) that lasts for several days.

• You notice green or yellow nasal discharge, which could be a sign of a bacterial infection.

• You have difficulty breathing or shortness of breath along with a runny nose.

• You have swelling around the eyes, which may be a sign of a more serious condition.

• Your runny nose is accompanied by a sore throat, cough, or other unusual symptoms.

• You have underlying health conditions (e.g., asthma, allergies, or a weakened immune system) that could complicate the condition.

• You experience ear pain or pressure, which could indicate an ear infection.

• A runny nose occurs in a newborn or infant, as they are more susceptible to complications from nasal congestion.

If you experience any of these concerning symptoms, it’s important to seek medical attention to ensure proper diagnosis and treatment. At Reliable MD, we are here to help you manage your runny nose and any related symptoms. Our experienced team will assess your condition and provide the care you need to recover quickly and safely.

At Reliable MD, we understand how uncomfortable sinus congestion can be. Many people believe that simply blowing their nose will clear out their sinuses, but the truth is a bit more complex. While blowing your nose can provide temporary relief by removing mucus from the nasal passages, it may not be effective in clearing the mucus from the deeper sinus cavities, where it often becomes trapped. The pressure created by blowing your nose can sometimes even push mucus further into the sinuses, leading to more discomfort.

The sinuses are hollow cavities located deeper within the face and skull, and mucus can accumulate in these areas during a sinus infection or allergy flare-up. To help clear the sinuses, it’s often more effective to use other methods, such as staying hydrated, using a saline nasal spray, or performing a gentle nasal irrigation (like a neti pot) to flush out mucus from the sinus cavities.

These techniques help relieve the pressure and promote the flow of mucus from the sinuses more effectively. If you’re experiencing persistent sinus congestion or discomfort, Reliable MD is here to help. Our skilled team can assess your symptoms and provide treatments to help alleviate sinus congestion and restore your comfort.
