I am allergic to cat and dog dander, tree, grass, flower pollen. A lot of antibiotics. Some foods.
Effects= I take lots of medication, and I have been to the emergency twice on the edge of anaphylactic shock . I have had my rings cut off, and my joints in ankle and wrist bigger than softballs. I have had prednisone for months at a time to get over that.
I have a lot of allegies. When being funny one day, the Dr. said "Let's assume you are allergic to everything and go from there."
Asthma is part of the effects also.
Over the years, I have learned to manage and take pretty good care.
