Thanks for the invitation. Generally, the common itchy skin is urticaria, which can be mild or severe, and in some cases can be accompanied by anaphylactic shock, requiring prompt resuscitation. Some last for a few minutes while others can last for a few days, and if the itching persists for more than 6 weeks, it is called chronic urticaria.

Common causes of hives include: 1) food and food additive allergies, such as seafood, eggs, etc.; 2) environmental factors from pollen; 3) medications, such as antibiotics, painkillers, etc.; 4) mosquito bites; and 5) autoimmune disorders, which are now found to be an autoimmune problem in about 40% of people with chronic hives.

The exact cause of the allergy needs to be determined by doing a laboratory test, while some patients cannot find out the exact cause even after a detailed examination.

Treatment is usually based on the cause of the disease, away from allergens, but can not find out the cause and relief of symptoms, you need to take antihistamines symptomatic treatment, severe patients need glucocorticoids or immunosuppressive drugs. I hope this helps.

Intense itching, any skin rashes? Is it related to diet? Are you cold or hot? Is the skin dry? It's hard to diagnose with just an itch, it takes a combination of your medical history, and plenty of symptoms.
