There are a lot of serious allergies; I know a woman who, like you, had a problem with certain scents...ruined her social life, she couldn't go anywhere without running into someone wearing something she was seriously allergic to.
My mother has that problem when people wear a musk based perfume. It constricts my mother's throat.
I get something similar. I can drink orange juice, or grapefruit juice (thought I don't particularly like grapefruit juice), and I can drink vodka, BUT, I can't mix the orange or grapefrut juices with vodka. As soon as I do that, one drink and my throat feels like it swells inside to where its difficult to swallow.
