Most bee stings heal themselves in 1-2 days if the symptoms are not severe, i.e., the redness, swelling, and pain are mild and no stinger remains. If the symptoms are more severe, they may heal themselves in 3-5 days. Bee stings can inject toxic substances that are acidic and can cause the body to have a metabolic reaction, resulting in painful, red and swollen bumps. At home, you can flush with soapy water to neutralize the acidic toxin and apply a cold compress to relieve symptoms. If the sting is severe and the stinger remains, causing an allergic reaction, or if the sting is caused by a large number of bees, it usually does not heal on its own and should be treated by a doctor. The doctor will first flush the sting, usually with an antiseptic such as iodophor, and then pull out the stinger to avoid further irritation and to control the further development of the infection. If an allergic reaction occurs, medication such as chlorpheniramine maleate can be taken as prescribed by the doctor. If the injured person experiences a drop in blood pressure, chest tightness, difficulty in breathing, or even shock, first aid should be administered promptly to quickly control and correct the manifestations of shock. Antibiotic drugs can also be used prophylactically to reduce the risk of infection. In addition, it is important to avoid scratching during the recovery phase after a bee sting, to disinfect and clean the wounded area regularly after proper treatment, and to abstain from eating spicy and irritating foods, seafood, smoking and alcohol to avoid promoting the spread of bee venom and aggravating local symptoms.
