When you are bitten, you should immediately check if there are any thorns inside. If there are any thorns, pick them out immediately. Don’t be afraid of the pain because the thorns are poisonous and will cause itching and red rash the next day. In severe cases, it will spread to a large area of ??surrounding skin. You can put some toothpaste on it, because bee venom is acidic, and toothpaste is alkaline and can neutralize toxins. You can also put some cooling oil on it, or go to the drugstore to buy some heat-clearing and detoxifying ointment. Generally, it will subside in three or four days.
