WebMD suggests putting a paste of baking soda and water directly on the sting site. An ice pack can also be applied to relieve pain and swelling. If the site is itchy, calamine lotion may be helpful.
If possible, remove the stinger. WebMD suggests scraping a fingernail or a pair of tweezers over the site to knock the stinger out. Elevate the limb to reduce swelling. Medications like ibuprofen and antihistamines can help relieve the pain and itching. In most cases, a bee sting causes only minor discomfort for a few days. If signs of a severe allergic reaction emerge, such as hives, a swollen tongue or difficulty breathing, seek emergency medical help immediately.
