If your body does not usually itch but itches after every bath, it is possible that you have an allergic reaction to the bath products, so you can change to other bath products. In addition, if your body is usually itchy and itches more after bathing, this is usually an allergic reaction caused by scratching or stimulation by hot water or bathing products, so you should pay attention to rinsing with water and bathing water should not be too hot. If the itching is serious, you can take levocetirizine or benzosuberastine tablets orally. If the oral medication does not relieve the itching for a period of time, it is recommended to go to the hospital to check the blood routine and allergens, and at the same time, you can take oral Chinese medicine to regulate the itching, and pay attention not to eat spicy seafood and other stimulating foods during the treatment period.
