What are allergies?
Allergies are an immune system reaction to a foreign substance, such as pollen, pet dander, dust mites, or certain foods. The body treats these substances as if they were dangerous, even though they are typically harmless. In response, the immune system releases chemicals that cause an allergic reaction. Common symptoms of allergies include sneezing, runny nose, itchy eyes, and skin rash.
What are the common symptoms of sickness?
The common symptoms of sickness include fever, fatigue, body aches, sore throat, coughing, and congestion. Other symptoms may include headache, nausea or vomiting, diarrhea, and muscle aches.
How can I tell the difference between allergies and sickness?
It can be difficult to tell the difference between allergies and sickness based on symptoms alone. However, allergies typically cause itchy eyes, sneezing, and a runny nose, while sickness generally causes fever, fatigue, body aches, and sore throat. If you're having any of these symptoms, it's important to speak to your doctor to determine the cause.
