What to do if your skin is itchy due to food allergies

When you experience itchy skin due to food allergies, stop eating the suspected allergenic food as soon as possible. If you develop large rashes, wheals, or even a little chest tightness and throat congestion at the same time, immediately take commonly used second-generation antihistamines. If the situation is not right, go to the emergency room immediately. Don't force yourself to do it or use folk remedies blindly.

When many people encounter this kind of situation, their first reaction is to either scratch it hard, or dig out the toothpaste, aloe vera gel, etc. at home and apply it on it. In fact, the probability of stepping on the trap is very high. Not long ago, the 7-year-old child of the neighbor downstairs ate less than half a mango. Within a few minutes, the area around his mouth turned red and he scratched his arm and complained of itching. The grandmother had to squeeze out toothpaste and apply it to the child on the spot. Fortunately, the child’s mother just got home from get off work and quickly gave the child the children’s version of cetirizine. She applied a soft cotton towel soaked in cold mineral water to the child for more than 20 minutes. The red mark basically disappeared. Later, I specifically asked a dermatologist I was familiar with, and he said that if I had applied toothpaste at that time, the mint and abrasives in it might have irritated the delicate skin that was already sensitive, and might even have caused contact dermatitis, which would be even more difficult to deal with.

Some people say that applying calamine lotion is especially effective if you have severe allergic itchiness. This is actually half right and half wrong. If the skin is only red and has a rash but no ulcers, applying calamine lotion can indeed quickly converge and relieve the itching. Applying it to the skin will quickly relieve the discomfort. However, if the scratch has been scratched and there is exudation, applying calamine lotion will irritate the wound, which can cause severe pain at best, or induce infection in worst cases, which will slow down the recovery.

If you happen to have a dinner outside and suddenly feel itchy due to common allergens such as seafood or nuts, don’t panic if you don’t have any medicine on hand. Don’t touch hot drinks or stay in a well-heated place. Heat will dilate blood vessels in the skin and release more histamine, which will only make the itching worse. Find a cool and ventilated place to sit. For a while, just ask your friends who are traveling with you to help you go to a nearby drugstore to buy commonly used medicines such as loratadine. If you still don’t feel relieved after half an hour after eating, or even feel a little labored to breathe and a little dizzy, don’t hesitate to call 120. When food allergies become serious, it is no joke to induce anaphylactic shock.

Don’t take it seriously if your allergy is gone this time. It’s best to wait about two weeks to go to the hospital for a food allergen test to find out which ingredient you are allergic to, and try to avoid it next time. I had a friend who was allergic to bromelain before. I didn't know it before. Every time he ate pineapple, he felt itchy. I thought it was because the pineapple was not soaked in salt water. Then he got itchy again and again after eating it. One time, half of his face even swelled. I went to get it checked and found out that it was an allergy. After that, I never dared to touch fresh pineapple again, and I never did it again. Don’t be too anxious. As long as you know the allergens clearly, read the ingredient list when you eat, and avoid allergenic ingredients, you will basically not suffer from this problem again.
