What are the itchy red bumps

If a person's body develops patches of red bumps that are very itchy, the first possibility is urticaria. Urticaria is local itching caused by allergies. There are many allergens, such as pollen and bacteria in the air, the food you eat, and the cleanliness of your clothes. It is difficult to determine the cause because the range of allergens is too large. However, urticaria is not a difficult disease. If it goes away quickly, it will disappear on its own. If it goes away slowly, it can be cured in 3-6 months by taking anti-allergic oral solution.

Urticaria is a localized edema reaction caused by dilation and increased permeability of small blood vessels in the skin and mucous membranes, commonly known as "wheals". It is characterized by the appearance of white or red rashes on the skin, which occur suddenly, have no specific location, appear and disappear from time to time, and are extremely itchy, and disappear without leaving any traces.

The cause of urticaria is allergic reaction. There are many factors that cause allergies, such as seasonal environmental factors, or food, clothing, pollen, cosmetics, etc. Treatment should start from two aspects: blocking allergens and anti-allergic treatment. Try to identify the cause of the disease and eliminate it. For example, be careful not to inhale pollen, animal dander, feathers, dust, castor powder, avoid contact with allergens, and prohibit or abstain from certain medications or foods that are allergic to the body. If the symptoms relapse due to hot or cold stimulation, you should not avoid them excessively. Instead, you should gradually introduce them and gradually extend the time of hot or cold stimulation in order to adapt to them. Actively treat primary diseases, such as acute tonsillitis, cholecystitis, viral hepatitis, appendicitis, intestinal ascariasis, etc., to eliminate the source of the disease. Keep a cheerful spirit and a good mood at ordinary times. At the same time, you should also pay attention to changes in temperature, add or remove clothes as the temperature changes, and strengthen physical exercise.

However, it is difficult for most patients to find the exact allergen. The treatment is to take oral anti-allergic drugs, which can be combined with calcium supplements, vitamin C, corticosteroids, etc. Chronic urticaria is sometimes difficult to treat and requires adjusting the body's immune function, such as taking Class II antihistamines for a long period of time (3-6 months).
