Grass pollen is a frequent cause of allergy symptoms. Common grass allergy symptoms can include:

• Sneezing;
• Stuffy nose (nasal congestion);
• Runny nose;
• Scratchy throat;
• Irritated eyes;
• Coughing;
• Wheezing.   

If you’re severely allergic to grass, you could even experience anaphylaxis.

Other Cross-Reactive Symptoms:

If you have a grass pollen allergy and have had an itchy mouth or throat after eating fresh fruit or raw vegetables, you may have Oral Allergy Syndrome (OAS). OAS is a cross-reaction that can occur when someone who is allergic to grass eats certain fresh fruits, vegetables, nuts, or beans and has an allergic response. For example, if you're allergic to grass, you may feel itching or swelling in your mouth after eating cantaloupe, honeydew, oranges, peanuts, peas, tomatoes, or watermelon.
