When symptoms like a runny nose, congestion, or sore throat appear suddenly, it’s not always clear what’s causing them. Many people in Philadelphia wonder whether they’re dealing with allergies vs cold symptoms and, more importantly, whether urgent care is needed. Because allergies and the common cold can feel very similar at first, it’s easy to delay care or choose the wrong treatment.
At Penn Medicine Becker ENT & Allergy, patients frequently ask how to tell the difference between cold or allergy symptoms and when it’s time to seek medical attention. Understanding the clues your body gives you can help protect your health and prevent symptoms from becoming more disruptive or prolonged.

What to Know at a Glance
- Many allergy symptoms last for weeks and are triggered by allergens rather than viruses.
- Cold symptoms usually develop quickly and resolve within about a week.
- Fever and body aches are more common with a cold than with seasonal allergies.
- Ongoing congestion or sinus pressure may benefit from ENT evaluation.
- Urgent care may be appropriate when symptoms worsen, persist, or interfere with breathing.

Understanding Allergies vs Cold Symptoms
Both seasonal allergies and the common cold affect the upper respiratory system, which is why symptoms often overlap. Sneezing, congestion, and a runny nose can occur with either condition. The key difference lies in the cause. Allergies are triggered by allergens such as pollen, dust mites, or pet dander, while colds are caused by viral infections.
Recognizing patterns, symptom duration, and associated signs can help determine which condition you’re facing and whether urgent care or an ENT visit is appropriate.
Signs Commonly Associated With Seasonal Allergies
Seasonal allergies occur when the immune system overreacts to harmless substances in the environment. In the Philadelphia region, pollen from trees, grasses, and weeds is a frequent trigger.
Seasonal allergy symptoms often include:
- Itchy eyes, nose, or throat
- Frequent sneezing
- Runny nose with clear drainage
- Stuffy nose that lingers for weeks
- Postnasal drip
- Symptoms that worsen outdoors or during specific seasons
Unlike infections, seasonal allergies do not cause fever. Allergy symptoms may come and go but often persist as long as exposure to allergens continues. Children and adults can both experience these symptoms, and untreated allergies may contribute to sinus pressure, fatigue, and sleep disruption over time.
Primary Symptoms of the Common Cold
The common cold is a viral illness that typically develops within a day or two of exposure. Cold symptoms often progress quickly and improve within seven to ten days.
Cold symptoms may include:
- Sore throat at the start of illness
- Stuffy nose or runny nose that changes color
- Mild fever, which is more common in children
- Body aches and fatigue
- Headache
- Cough that develops after congestion
Unlike seasonal allergies, cold symptoms usually resolve on their own with rest and supportive care. However, symptoms that worsen or fail to improve may require medical evaluation.

Overlapping Symptoms That Can Be Confusing
Some symptoms appear in both allergies and colds, which is why many people struggle to tell the difference. A runny nose, nasal congestion, sneezing, and throat irritation can occur in both conditions.
Key clues often come from timing and duration. Seasonal allergy symptoms may last for weeks or months, while cold symptoms usually follow a shorter course. Allergy symptoms also tend to improve indoors or when allergens are reduced, while viral infections do not follow this pattern.
Why an Accurate Diagnosis Matters
Mistaking allergies for a cold can delay effective treatment, while assuming a cold is “just allergies” may lead to unnecessary discomfort. Ongoing nasal inflammation from untreated allergies can increase the risk of sinus infections, ear pressure, and sleep issues. Repeated viral infections may also strain the immune system, particularly in children.
At Penn Medicine Becker ENT & Allergy, accurate diagnosis allows providers to recommend treatments that are appropriate for the cause of symptoms rather than relying on trial and error.
When Cold or Allergy Symptoms May Require Urgent Care
Most mild symptoms do not require urgent care. However, certain warning signs suggest that medical evaluation should not be delayed.

Seek urgent care or prompt medical attention if symptoms include:
- Difficulty breathing or wheezing
- High or persistent fever
- Severe facial pain or pressure
- Swelling around the eyes or nose
- Symptoms that worsen instead of improving
- Signs of dehydration in a child
Urgent care can help rule out complications and determine whether symptoms are related to infection, allergic inflammation, or another underlying condition.
How ENT Evaluation Supports Better Outcomes
An ENT specialist focuses on conditions affecting the ears, nose, and throat. For patients with frequent congestion, sinus pressure, or recurring symptoms, ENT evaluation can help identify contributing factors that urgent care alone may not address.
Diagnostic tools may include a detailed symptom review, nasal examination, or allergy testing when appropriate. Identifying specific allergens allows for targeted treatment rather than repeated short-term relief.

What to Expect During Your Appointment
During your appointment, providers take time to understand symptom patterns, duration, and impact on daily life. Patients are encouraged to describe when symptoms occur, what seems to make them worse, and how they respond to over-the-counter medications.
This information helps determine whether symptoms are more consistent with a common cold, seasonal allergies, or another ENT-related condition. From there, a clear care plan can be discussed.
