About 3 months ago I went to the dr and was diagnosed with allergic rhinitis. I got tested for allergies, saw an ENT, had a ct scan done (was clear), and still don't feel any better. I wake up everyday with severe nasal congestion and post nasal drip. Having trouble focusing, have eye floaters, fatigue, feel like I'm living outside my body. Is all this being caused by hay fever? I am 30 years old and have never had severe allergies. I exercise regularly and always have a positive outlook on life, but I have been miserable for months! HELP!
