The most common allergy symptom is the wheeze that you hear when you breathe. This can be caused by a build-up of mucus in your lungs. If you are not used to having this condition then it can be quite embarrassing and difficult to deal with.
Wheezing is usually the first thing that people notice when they have an allergic reaction. This is especially true if it is caused by something you are allergic too. People with asthma are at high risk of developing allergies due to their condition. It is important to know what allergens you are allergic to so that you can protect yourself against them.
