Can Allergies Feel Like the Flu?

Picture of a woman sitting under a blanket and sneezing.Ah, allergies—you know the feeling all too well. Or so you think. Because during flu season, you might start questioning whether something more serious—like influenza—could be causing your symptoms. Can allergies feel like the flu? And if so, how do you tell these two conditions apart? We’ve got the answers you need.

Common Symptoms

The following symptoms can be indicative of either allergies or a flu infection, making it difficult to tell what’s actually at the root of your illness:

  • Sneezing
  • Runny nose
  • Congestion
  • Sore throat
  • Coughing
  • Headache
  • Fatigue

Differing Symptoms

The only way to truly know what’s causing your symptoms is to visit a trained medical provider, who will be able to evaluate your condition and provide you with an accurate diagnosis. With that being said, there are a few key differences between allergy and flu symptoms that can make it easier to distinguish between the two conditions:

  • Fever – If your temperature is higher than normal, you probably have the flu or something else, since allergies typically don’t cause a fever.
  • Itchiness – The flu usually doesn’t cause itchiness, so if you’re experiencing itchy or watery eyes, you more than likely have allergies.
  • Body aches – Although the inflammation caused by allergies can sometimes lead to achiness, body aches are much more commonly associated with the flu.

What Causes Each Condition?

If you’re trying to determine whether you have allergies or the flu, it can also be helpful to think about what might have led to the sickness. An allergic reaction occurs when someone’s immune system mistakenly identifies a normally harmless substance as dangerous, and then takes the steps necessary to fight it off. Some common allergens include pollen and animal dander. So, if you started feeling under the weather after spending time outdoors or with a friend’s new pet, then chances are good that you might be experiencing allergies.

The flu, on the other hand, is a viral infection caused by various influenza viruses. According to the Centers for Disease Control and Prevention (CDC), most experts believe that these viruses are primarily spread through airborne droplets produced when an infected person sneezes, coughs, or talks. The flu can also be contracted when someone touches a contaminated surface and then touches their nose, mouth, or eyes. So, if you’ve recently been in contact with someone who was diagnosed with influenza, then it’s likely you could also have the flu.

"The overall care I received was excellent! I also appreciate your affiliation with Yale New Haven Hospital."

Patient
Derby, CT

"Throughout the visit I felt like the staff really cared. The Doctor took his time talking with me about my symptoms, and I felt like he listened to all my concerns and took that into consideration when recommending the right treatment. Thank you!"

Patient
Hamden, CT

"I had to take my son in for an ear infection following a sudden change in temperament at daycare. He was inconsolable the entire car ride but when we got there and by the time we left this care facility he was back to his normal happy go lucky little two year old boy. I highly recommend PhysicianOne Urgent Care."

Patient
Westwood, MA

"I wanted to take a moment to thank you for the attention you gave me last week. My son was started on antibiotics and ear drops. Within 24 hours he began to feel better. The poor kid had been going to school in tears because he was afraid of missing any more days, but feeling (and looking) just awful! He's not been able to even think about lacrosse practice, but thanks to starting him on antibiotics, he was thrilled to return to practice today."
