Why does it itch after being stung by a bee?

A patient who feels itchy after being stung by a bee is considered to have had an allergic reaction to the bee sting. The principles of treatment for bee stings include treating the wound as soon as possible, sucking out the poisonous needles, and preventing allergic reactions. Because the poisonous needles and stings in bees can easily cause anaphylaxis, patients must pay high attention to avoid anaphylaxis if they develop itchy skin and red patches, pimples, and allergic hives on their bodies. The patient should be treated quickly at a hospital where the doctor will thoroughly clean and disinfect the wound. If there is a poisonous thorn in the wound, it will be picked out with a sealed alone, and the wound can be disinfected by applying iodophor or rinsed with potassium permanganate solution afterwards. In addition, local treatment should be done by rubbing flouro easy or corticosteroid ointment. If there is obvious circumscribed itching, oral chlorpheniramine, loratadine, cetirizine and other drugs should be given for desensitization.
