It's hot every year, and my palms are still itchy. What's wrong with it? How to treat it?

Hello, this situation is caused by urticaria or allergies, local eczema and other uncomfortable symptoms. I suggest you go to the hospital to check allergens, pay attention to hygiene, fast spicy food, don't scratch to avoid infection, consider taking antiallergic drugs under the guidance of a doctor, and pay attention to strengthening nutrition.
