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.
Some people may have a stronger allergic reaction to an insect's venom, leading to bee sting side effects, such as a very large, swollen welt. The welt may grow in size over a 48-hour period. This reaction remains local to the sting site and doesn't spread to other areas of the body.
You probably won't have a severe allergic reaction the first time you are stung. But even if your first reaction to a sting is mild, allergic reactions can get worse with each sting. Your next reaction may be more severe or even deadly.
Stinging insect allergies can worsen over time. So, it is crucial to contact an allergist and discover your risk for anaphylaxis with your next sting. By taking action, you can prevent an emergency. Also, consider how you were able to respond in the first few minutes after the incident.
Severe pain or burning at the site lasts 1 to 2 hours. Normal swelling from venom can increase for 48 hours after the sting. The redness can last 3 days. The swelling can last 7 days.
A less common — but still potentially very dangerous — reaction to an insect sting is bee sting serum sickness. In this instance, your immune system reacts to the foreign toxin introduced into your body by the bee sting. Typically, bee sting serum sickness occurs a few days or a week after the insect sting.
The majority of the time, the symptoms of bee sting serum sickness will improve on their own within 48 hours. As the chemical from the bee toxin is filtered out of your body, the sickness will begin to go away.
You may have an allergy to bee venom, which can cause a severe allergic reaction that requires immediate medical attention and can be life-threatening if left untreated. If you were stung by a bee and experience symptoms like difficulty breathing or dizziness, call 911 or go to the emergency room (ER).
A bee sting may cause an allergic reaction or anaphylaxis. Symptoms of a severe allergic reaction can vary, but may include hives, a swollen throat or tongue, flushed skin, nausea, vomiting, dizziness, and more. For most people, a bee sting only produces temporary pain and irritation at the site of the sting.
Reactions occurring more than four hours after a bee or other insect sting are classified as delayed reactions. There have been isolated reports of serum sickness-like syndromes occurring about a week after a sting.
Seek prompt medical care if you've been swarmed by bees and have multiple stings. Make an appointment to see your doctor if: Bee sting symptoms don't go away within a few days. You've had other symptoms of an allergic response to a bee sting.
A normal reaction results in pain, swelling, and redness around the sting site. A large local reaction results in redness and swelling that extends beyond the sting site. The swelling may extend about 4 inches from the sting site over a period of a couple of days. It should get better within 5 to 10 days.
Normal reactions typically include intense pain, itching, and redness with swelling at the sting site up to the size of quarter. Large local reactions extend out from the site of the sting and involve redness with swelling that can at times involve the entire arm or leg.
Bites and stings may become infected. Signs of infection include redness, warmth, pain, redness streaking up the arm, drainage of pus, and swelling. Infections will need treatment with antibiotics and should get better over the next 10 days.
Step 1: Take Out the Stinger
You'll likely see a red bump. If a stinger was left behind, you'll also see a small black filament sticking out of the center. It may have a bulbous end, which is the venom sac. If the skin around the stinger is loose, pull it tight to get a better look.
Medical Treatment for Bee and Wasp Stings
If you have a single sting with no allergic symptoms, you may require only local wound care such as cleaning and applying antibiotic ointment. Any stingers that remain will be removed. And you may be given an oral antihistamine to treat itching.
If bee stings are left untreated it can cause a life-threatening condition known as anaphylaxis.
Trouble breathing. Hives that appear as a red, itchy rash and spread to areas beyond the sting. Swelling of the face, throat, or any part of the mouth or tongue. Wheezing or trouble swallowing.
If the reaction starts spreading, it's time to seek bee sting emergency treatment, particularly if you have a known allergy to bees or are suffering from multiple bee stings. Other severe allergic reaction symptoms to watch for include: Skin irritation such as hives, itching, and/or flushed or pale skin.
A person with a bee sting will likely experience severe pain for one to two hours after getting stung. After intense pain, the area will start to become itchy. Redness, pain, and swelling can last up to seven days after the incident. This is for someone not allergic to bee stings.
Epinephrine is a medication that can help to reduce bee sting allergy symptoms. You may also need to be treated with antihistamines and cortisone through an IV. Your doctor will likely prescribe an epinephrine auto-injector to carry with you at all times.
Large Local Reactions and Bee Sting Swelling Days Later
A local reaction can produce very uncomfortable pain, itching, and swelling. Some of this swelling can be delayed, increasing over 24 to 48 hours. It may take 3 to 10 days for these symptoms to resolve.
Baking soda, when mixed with water, is said to help neutralize bee venom, reducing pain, itching, and swelling. Mix baking soda with enough water to make a paste, then apply a generous amount onto the affected area. Cover the area with a bandage, then leave it on for at least 15 minutes. Reapply, as needed.
Apply hydrocortisone cream or calamine lotion to ease redness, itching or swelling. If itching or swelling is bothersome, take an oral antihistamine that contains diphenhydramine (Benadryl) or chlorpheniramine. Avoid scratching the sting area.
