Allergies can cause symptoms that are very similar to a cold or flu, such as a runny nose, sore throat, or sneezing. However, allergies do not cause a fever. Because each allergy has a different underlying cause, it is essential that a person receives the right diagnosis, so that they can get the best treatment.
