Can allergies cause a fever? — Home GP for a fever in Sotogrande

Home GP for a fever in Sotogrande

Allergies don't cause fever, but they may cause sinus infections and fevers. Bacterial or viral illnesses may mimic allergies and produce fevers. In this article, we will cover potential reasons for fever as well as the symptoms of allergies. We also look at the treatment options available and when to call our Home GP for a fever in Sotogrande.


Can allergies cause fever?

According to our Home GP for a fever in Sotogrande allergies do not cause a fever.

If a person has a fever in addition to allergy symptoms, such as a runny or stuffy nose, then the individual most likely has a sinus infection.

A person who has hay fever, also known as allergic rhinitis, will not have a temperature because of their condition. Pollen, mould, and pet dander are just a few of the environmental factors that may set off allergic rhinitis symptoms in susceptible individuals.

Those who suffer from allergic rhinitis or asthma are more prone to develop chronic sinus infections, which have the potential to bring on a fever. Allergic rhinitis does not bring on a fever on its own.

Our Home GP for a fever in Sotogrande notes that this is because the presence of allergic rhinitis  or asthma can lead to inflammation of the airways.


Common allergy symptoms

Allergy symptoms can include:

  • runny or congested nose
  • sneezing
  • congestion
  • irritated, watery eyes
  • nasal and oral lining irritation
  • coughing
  • wheezing
  • breathing difficulty
  • chest constriction
  • nausea
  • both hives and skin rashes
  • fatigue
  • vomiting
  • headache


What can cause allergy symptoms and fever?

In addition to a fever, a person infected with a virus may have symptoms that are similar to those of an allergic reaction.

One of the most obvious signs that a person has allergies is that the symptoms of allergies only continue for as long as the person continues to be exposed to the allergen that causes them. Other culprits, such as the influenza virus or the common cold, tend to have a considerably longer incubation period.

Also, a person suffering from allergies will have eyes that are both itchy and watery. This symptom does not generally appear concurrently with a cold or the flu.



The inflammation of a person's sinuses is known as sinusitis. These are hollow cavities that may be seen in the face, particularly around the cheeks, nose, and eye region. The sinuses produce mucus, which helps maintain a regular airflow.

On the other hand, if the sinuses get inflamed, the mucus may not be able to drain as it should and it could begin to accumulate.

In most cases, an illness such as a cold or the flu will precede the onset of sinusitis symptoms.

In severe instances of acute sinusitis, a fever may develop in the affected individual.

Additional symptoms that may accompany acute sinusitis include the following:


  • forehead and cheek discomfort
  • post-nasal drip
  • thick nasal discharge that is yellow or green in colour
  • cough
  • congestion
  • toothache


Since both allergies and the flu influence the respiratory system, comparable symptoms may be experienced by those who suffer from either ailment.

The flu may give you a fever that might persist anywhere from three to four days.

Other signs and symptoms of the flu may include the following:

  • blocked or runny nose
  • chest congestion
  • headache
  • cough
  • sore throat
  • physical aches and pains
  • fatigue

Allergies are more likely than the flu to cause itchy, watery eyes.

Common cold

The root cause of a cold in most people is an infection with a virus.

It is possible for someone who has a cold to develop a fever as well as chills, but this is a rather rare occurrence.

Typical symptoms are as follows:

  • body aches
  • coughing
  • headaches
  • sneezing
  • throat pain
  • runny or blocked nose
