My neck itches and turns red when I scratch it

Itching may seem like a normal little thing, but in fact it may be hiding a serious problem. Some people just scratch their neck when it itches, but this does not solve the problem and causes the skin to turn red. This is most likely caused by allergies, but there are other possibilities. Everyone must find the cause and then treat it correctly.

The skin is a relatively sensitive soft tissue, and people need to be well protected for the skin. However, many people's skin is prone to problems, such as acne and itchy skin, which are manifestations of skin problems. The most common phenomenon is an itchy neck with small red bumps, which makes many people feel very uncomfortable.

An itchy neck with small red bumps is a typical allergic condition.

Allergic constitution generally refers to people who are prone to allergic reactions and allergic diseases but cannot find the cause of the disease. This is called "allergic constitution." People with "allergic constitution" may suffer from various allergic reactions and allergic diseases, such as eczema, urticaria, allergic asthma, and some are particularly sensitive to certain drugs, which may cause drug-induced dermatitis or even exfoliative dermatitis.

1. Dermatitis. However, occasional high reactivity to a known factor cannot be called "allergic constitution."

2. Food: seafood, shellfish, peanuts, eggs, milk, coffee, mango and other foods containing high levels of protein and spicy foods.

3. Plants: pollen, aloe, Citrus, Moraceae, Anacardiaceae, seaweed, etc.

4. Medicines: aspirin, penicillin, analgesics, sedatives, antibiotics, contraceptives, etc.

5. Chemical substances: hair dye, pesticides, paint, preservatives, sunscreen, alcohol, fragrances, artificial colors, perm agents, rubber, gasoline, etc.

6. Metal substances: gold, silver, copper, mercury, lead and nickel.

7. Others: animal fur, leather goods, fibers, and insect bites.

The most important thing for people with allergies is to avoid contact with allergy-causing substances as much as possible, because with each additional contact, the body will have an additional immune substance against the allergens, and the reaction will be more intense; on the contrary, if there is no contact with allergens for a long time, the corresponding antibodies or lymphocytes will gradually decrease, and the allergic reaction will gradually disappear on its own.
