Hi, I am 26 and allergic to indoor allergens as well as some outside. I have went quite a while without a nose spray or antihistamine being ok. Then i will get stuffy/sinus pressure. My Dr ordered a CT scan a year ago and said i had a deviated septum and some nasal polyps. I generally take Flonase. About a week ago the allergies and sinuses really got a hold of me and i had horrible sinus pressure, felt really spacey, had ear fullness and pain, felt a little off but no ear infection. I got put on a antibiotic. I then just started the Flonase back up. One day i felt short of breath off and on. I also took a Zyrtec. I almost went to the hospital because i felt bad and felt like my allergies/ sinuses were causing it. I also have anxiety. I see my Doctor next week but my questions are: Could that have been Allergy induced Asthma? Could it start now even though i am 26? And how common is Multiple Chemical Sensitivity? And can Perinnial Rhinitus Allergies get worse with time?Sometimes i'm not sure if it's allergies causing my symptoms or anxiety. Thank you!
