I've had very bad allergies since I was a child. My allergies have caused me to have breathing problems and wind up using a breathing machine even though I don't have asthma. I have to take an allergy pill every day and also use an allergy nasal spray every day, and depending on how bad my allergies are I wind up using a breathing machine some times each year. So, yes, my allergies are bad but I'm not afraid anymore because I am learning how to control them.
