How do you know what has caused an allergic reaction?

Answer 1

Try to figure it out by process of elimination. First consider in the last week or two what you have eaten that you have not had before, or for a while. Then check to see if you are using a different brand of bath soap or laundry detergent. Think of anything that you have touched or consumed that is different from what you usually eat. If your reaction is gone, it may be what you ate. You could eat it again and see if you get the same reaction. But if you are still reacting, it may be something around the house. Start by changing soaps. Change or eliminate only one thing at a time so you will know when you find it. If you are still having trouble you can be tested for Allergies at a dermatologist's office. Our systems change and we can become allergic to things that didn't bother us before. We can also stop having allergic reactions to things we were before.
