Juniper trees are a common source of allergies due to the pollen they create. Individuals with a juniper allergy are said to have seasonal allergies, meaning the symptoms flare up only when the tree is producing pollens. In some parts of the United States, this means spring allergies, but in western states the pollen can come from mountain cedar, also a juniper tree. Symptoms of seasonal allergies are mostly the same regardless of the allergen.
An itchy throat, nose, eyes, ears and/or the roof of the mouth are the earliest symptoms of a juniper allergy, states the Merck Manual. This can be abrupt or increase over time. Taking allergy medications at this point can prevent further discomfort.
Allergic rhinitis is excessive mucus production that results in a clear, watery nasal discharge, sneezing and congestion. Congestion occurs because the blood vessels in the nasal passages become inflamed and swell closer together. This creates the stuffy feeling of an allergy. Postnasal drip can also develop with allergies of this type, and involves the noticeable drainage of thick mucus down the back of the throat. Normal mucus production goes mostly unnoticed, but this thicker mucus can give an individual the sensation of a lump in the throat when swallowing. It can also contribute to bad breath.
A sinus headache can accompany pollen allergies. This type of headache occurs in the forehead, behind the eyes or in the face near the nose. Pain in these areas is due to the congestion in the sinus cavities nearby.
The eyes can become red from inflammation caused by juniper pollen. Some individuals may experience eye watering and have trouble wearing contact lenses due to the discomfort. This symptom of allergies is called allergic conjunctivitis.
Juniper pollen can cause coughing and wheezing. Individuals with asthma may experience more frequent or worsened attacks, according to Merck Manual.
Fatigue can result from allergy symptoms, suggests the Allergy, Asthma and Immunology Clinic of Georgetown. Individuals may struggle to sleep during peak pollen season due to the discomfort of the other allergy symptoms.
