An allergic reaction occurs naturally when your body receives fallen materials or substances that are highly sensitive to it. Bodies react differently to different substances and that’ explains why people are not allergic to same things. Also, the rates of allergic reactions vary from mild, like that of a small rash, to harsh reactions that can be serious. Below are some of the major symptoms that show an allergic reaction and why you need an allergy testing.
1. Sneezing, Running nose
Sneezing is common to people, but you need an allergy testing to ascertain that an allergic reaction causes it. Allergic rhinitis is the allergy reaction in the nose and characterized by congestion, runny nose, sneezing, and also itching in your eyes, nose, or top of your mouth. Some of the other conditions that can cause sneezing include sinus infection, non-allergic rhinitis, overuse of the decongestant nasal spray, etc.
2. Shortness of breath
Breath shortage is the major cause of asthma and occurs when you exhale. Wheezing is caused by narrowing and swelling of the airways to lungs or throat. It can also cause a shortage of breath since your lungs can’t hold enough air when they have mucus or swelling. However, you need an allergy testing since wheezing in children below the age of five years can be as a result of the cold. Shortage of breath is triggered by dust mites, pollen, ragweed, animal dander, etc.
A rash is a condition that alters the normal feel or appearance of your skin. It might be itchy or painful making your skin to be dry, bumpy, red, cracked, warm, or blistered. The condition can be caused by milk, eggs, or food allergy. At times it might be hard to tell whether the rash you are experiencing is as a result of an allergy, no wonder you need an allergy testing. Some of the major skin rashes affiliated with allergy include hives, eczema, and contact dermatitis.
4. Nausea and vomiting
Food allergies are the major causes of vomiting and nausea. A reaction happens when your immune systems react to something highly sensitive to the food, and your systems automatically incorrectly register as dangerous and harmful to your body. However, seasonal allergies are not associated with nausea. In any case, seasonal allergies include rash, itchy eyes, sneezing, and a runny nose. If you come across a substance you are allergic to, your immune systems regard it as harmful, and it releases histamine to fight the harmful substance.
5. A headache
You might experience a headache from different causes, but migraines and sinus headaches are highly linked to allergies. A sinus headache manifests around the sinus area and may also come in the form of pain on your face. A migraine headache is usually a severe pain on one side of your head. It may make you experience nausea, and light highly accelerates it.
An allergic reaction may result due to very many things and may affect any part of your body depending on the allergens. Once you experience any symptoms, you need to undergo allergy testing before you conclude what is ailing you.
