Is It Allergies or Infections? Distinguishing Between Symptoms

Allergies are immune reactions to substances known as allergens, like pollen, dust mites, or pet dander. Symptoms often include sneezing, itching, and a runny nose.

Infections are caused by pathogens such as bacteria, viruses, or fungi. Common symptoms include fever, body aches, and fatigue. It's vital to understand that infections can produce similar symptoms to allergies but typically have additional signs.

List out your symptoms. Allergies typically manifest with clear nasal discharge, while bacterial infections often cause thick, yellow-green mucus. Fever is common with infections but rare in allergies.

Allergy symptoms can persist for weeks, especially during specific seasons or exposure to allergens. Infections usually have a clear onset and often resolve within a week or two if left untreated.

Consider recent activities that might have exposed you to allergens, like yard work or pet interaction. Infections may follow a cold or flu exposure or come on without clear external triggers.

Fever, body aches, and chills can indicate an infection. Allergies do not typically cause body aches or fever, though they can lead to fatigue over time.

Sometimes, a doctor can identify signs of an infection through a physical exam. This may include checking for swollen lymph nodes, unusual skin eruptions, or respiratory issues.

If symptoms are persistent or severe, it’s important to see a doctor for a proper diagnosis. They may prescribe tests like blood tests or allergy tests to further evaluate your condition.

For allergic reactions, over-the-counter medications like antihistamines can provide relief. Infections may require antibiotics if bacterial, while viral infections generally resolve over time with rest and hydration.

Keep track of your symptoms and responses to treatment. If allergies are treated and symptoms persist, reevaluation is necessary to rule out infections.
