I have had a sore throat for a few days, there is some pain when I swallow and my ears are itchy deep inside.? - nasal spray and throat pain

There is some pain on swallowing, and my ears are itching. As of today, there were some bottlenecks. Is this an infection or because of an allergy? I'm allergic to grass and I was often outside today, and I take my nasal spray for a few months
