Lately I've been experiencing something that feels/looks like an allergic reaction. Since about last year, after almost everything I eat, I feel nauseated. Then recently i had a drink of alcohol, and immediately my mouth (lips and tongue) were swollen, along with difficulty breathing. It also happend when I went to the dentist for a filling. Immediately after she injected me, my lips and tongue started swelling up, and I again had trouble breathing. I also couldn't swallow. And the other day, my friend dropped her glass of alcohol (I think it was a rev) and I accidently put my hand in it (I think I may have put my hand near my mouth afterwards), then about 15 minutes later I started feeling weird (nauseated, dizzy, started having weird rashes all over, my tongue and lips were starting to swell, ...).
The foods that mostly makes me feel nauseated are, shrimps, lobster, some fuits, every kind of juice, bread, and a lot more.
Also, I had severe eczema when I was young, then it dissapeared for awhile, but came back a few months ago when my mother changed the laundry detergent. I also noticed that shampoos, soaps, etc., gives me rashes all over my body (where it touched).
Could this be an allergy to sulfates/sulfites (not sure which one)?
And should I be carrying an epi-pen?
