A 25-year-old female presents with itchy eyes, sneezing, and a runny nose. She reports that these symptoms recur every spring. What is the likely diagnosis and initial treatment plan?
The patient's symptoms are indicative of seasonal allergic rhinitis, commonly known as hay fever, likely triggered by pollen exposure in the spring. The initial treatment plan should involve avoidance of allergens if possible, along with symptomatic treatment using antihistamines for the itching and sneezing, and a nasal corticosteroid spray for nasal congestion.
