Symptoms
Bee stings can produce different reactions, ranging from temporary pain and discomfort to a severe allergic reaction. Having one type of reaction doesn't mean you'll always have the same reaction every time you're stung or that the next reaction will necessarily be more severe. Mild reaction
Most of the time, bee sting symptoms are minor and include: Instant, sharp burning pain at the sting site
A red welt at the sting area
Slight swelling around the sting area
In most people, the swelling and pain go away within a few hours. Moderate reaction
Some people who get stung by a bee or other insect have a bit stronger reaction, with signs and symptoms such as: Extreme redness
Swelling at the site of the sting that gradually enlarges over the next day or two
Moderate reactions tend to resolve over five to 10 days. Having a moderate reaction doesn't mean you'll have a severe allergic reaction the next time you're stung. But some people develop similar moderate reactions each time they're stung. If this happens to you, talk to your doctor about treatment and prevention, especially if the reaction becomes more severe each time. Severe allergic reaction
A severe allergic reaction (anaphylaxis) to bee stings is potentially life-threatening and requires emergency treatment.
