What Causes Sickness, Dizziness And Nausea After Using Flonase Nasal Spray?

my ear hurts deep inside the ear canal like on the sides. when i stick my finger in and press them on the side i feel what i think is ear wax and i want to scrape it off but i cant. i feel like if i can remove whatever is stuck on the sides the pain will go away but i cant. i went to the doctor and he told me he could see my eardrum just fine and he prescribed flonase nasal spray which i only used once because im not sick and the side effects were terrible. i was dizzy i couldnt sleep all night and felt nauseous.
