Hay fever: Symptoms after exposure to tree pollen

Hay fever affects millions of individuals all over the globe. The symptoms are usually triggered by the abundant airborne tree pollen in the environment. The common sources of allergy-inducing pollen include oak, birch, elm and sycamore trees. Always bear in mind that children are highly susceptible to these allergies. The signs and symptoms of hay fever can range from the usual nasal issues or even oral allergy syndrome.

Nasal symptoms after exposure to tree pollen

Many individuals link itchy and runny nose with the spring time allergy symptoms of hay fever. The airborne tree pollen can enter the nostrils and irritate the sensitive lining of the skin which triggers the release of histamine.

Itchy and watery eyes can occur with nasal symptoms along with sneezing as a reaction to the irritant and coughing from the excess mucus.

What are the facial symptoms?

If the individual experienced prolonged tree pollen allergy symptoms, he/she can develop the facial indications of the allergy. The increased flow of blood in the sinus area can lead to dark circles below the eyes which are called allergic shiners.

The broken blood vessels in the nose and cheek area might develop due to the increased flow of blood, eye rubbing and nose blowing. Among children, if there is repeated, upward wiping of the nose, it is called an allergy salute that can cause an evident crease on the nose.

Early treatment of the allergy symptoms by a doctor for the prolonged tree pollen symptoms can help avoid the facial symptoms of hay fever.

Once an individual with hay fever consumes these cross-related foods, the oral symptoms of hives, itchy mouth, itchy ears and swollen mouth or throat can develop.

What is oral allergy syndrome?

A link between the proteins of tree pollen and certain foods can lead to the development of the symptoms of oral allergy syndrome especially among older children and adults who previously experienced the symptoms of seasonal hay fever. The tree pollens typically linked with the oral symptoms from food includes the birch tree pollen. The protein from this pollen shares the characteristics with fresh fruits such as pear, apple, plums, peach and cherries. In addition, hazelnuts and almonds also have resemblances to the birch pollen as well.

Once an individual with hay fever consumes these cross-related foods, the oral symptoms of hives, itchy mouth, itchy ears and swollen mouth or throat can develop. In severe cases, the oral symptoms do not progress to generalized body symptoms and could not cause lasting effects. Nevertheless, serious reactions such as difficulty breathing or anaphylaxis can occur as well.

The contact reactions such as skin itchiness or hives after exposure to food can also develop in some individuals. If these cross-reacting foods are cooked, it changes the proteins that are similar to tree pollen. With this in mind, the cooked foods do not trigger the allergy symptoms after tree pollen reactions.
