Areas adjacent to the site of the skin may also be involved in the large local reaction. In a systemic allergic reaction, the entire body is affected. The victim may develop, redness, or swelling at sites on the body distant from the site of the sting. Symptoms can also include:, and.

Around 50 people are killed each year in the U. S. due to severe anaphylactic reactions to bee stings. These type of reactions usually occur within minutes of the bee sting. Since most people who have to bee stings will have a worsened reaction to every subsequent sting, those individuals with bee sting should talk to their doctor about taking special precautions, including carrying an injectable form of the drug epinephrine (used to treat anaphylactic reactions) at all times. Bees, wasps, hornets, yellow jackets: most people can't tell them apart. But they all sting - and there's no mistaking that sting! The pain is immediate and intense.

They worry that they're having an allergic reaction because the pain, itching, and swelling are so alarming. How can you tell the difference between a miserable sting and an actual allergic reaction? Anaphylaxis is the name for severe allergic reactions that can cause a person to collapse and die.
An anaphylactic reaction to a sting (or just about anything else) causes trouble breathing. This happens quickly, within minutes to an hour. The victim could have chest tightness and a feeling of tightness in the throat. The person could feel faint. Hives (red, itchy bumps on the skin) pop up away from the bite. This is a true medical emergency. Call 911 right away! If the person has a kit to treat allergic reactions, start using it immediately. (Follow directions to use the "Epi-Pen", a shot of epinephrine.

Expected effects are pain, swelling, redness, and itching. All effects are at that specific spot. Even if the area is still red, swollen, itchy, and painful the next day it's an expected reaction, not an allergic reaction. Treatment is in two parts: If there is a stinger in the skin, remove it gently. Scrape it out with something that's not sharp: a finger nail, the edge of a credit card, or the dull side of a knife. Do not use tweezers or fingers to grab the stinger and pull it out; that pushes more venom into the skin. Wash the area well with soap and water. Apply ice to help relieve itching, swelling, and pain. There's no one treatment that works all the time. You can apply a cortisone cream, an antihistamine cream, or a paste of baking soda and water. Treat severe itching with an antihistamine. Diphenhydramine (Benadryl ) and chlorpheniramine might help. Be sure to follow label instructions for dose and precautions; these drugs can cause sleepiness. Try an over-the-counter pain reliever for pain. In all cases, try to avoid scratching.

If you've been stung, Poison Control will stay in touch with you until your symptoms are no longer troublesome.
