I was born with my asthma, hereditary from my father's brother. My parents didn't know and I was always sick. When I got older I went to an allergist and got a million tests! I have 4++ on most all of my allergy test, 4 being the highest you can have! I started shots and a couple of drugs. I got a bit better but just got over double pneumonia, 3 days in the hospital. I am 74.
