Question: how do you know if you're allergic to grass?
Answer: Allergy to grasses is very common. Grass allergies can present in a variety of ways, including nasal symptoms (runny nose, stuffiness, sneezing), asthma, and eye symptoms (itchy, watery/red eyes). People can also have skin rashes (hives or skin welts) after exposure to grasses, but this is much less common.
