Sneezing and Runny Nose
These are hallmark symptoms of most allergies. Sneezing is a reflex to clear the nose of allergens, while a runny nose is due to inflammation and swelling causing an overproduction of mucus.
Congestion
Another response to an allergen like Sweetclover pollen is nasal congestion. This happens when the nasal tissues and blood vessels swell with excess fluid, causing a 'stuffy' feeling.
Itchy, Watery Eyes
Allergic reactions to Sweetclover pollen can often cause itchy eyes due to inflammation. This may lead to an increase in tear production, causing the eyes to become watery.
Wheezing and Shortness of Breath
If an allergic reaction is severe, it can cause an inflammatory response in the lungs leading to wheezing, difficulty in breathing, or shortness of breath.
Hives
Hives, or urticaria, present as red, itchy welts on the skin. This is a common symptom of an allergic reaction, similar to Sweetclover pollen allergies.
Sinus Pressure and Pain
Due to chronic congestion, some individuals may develop sinus pressure and pain. The swelling in the sinus cavity can cause a dull pressure-like sensation around the nose, eyes, and forehead.
