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.
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 large local reaction can be defined as swelling at the site of the sting exceeding 10 centimeters. These symptoms may continue developing for up to a few hours after the incident. If the sting happened on your arms or legs, the symptoms could last for days or weeks while still being considered a local reaction.
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.
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.
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. This will worsen itching and swelling and increase your risk of infection.
Symptoms of a severe allergic reaction (called an anaphylactic reaction or anaphylaxis) may include one or more of the following: Trouble breathing. Hives that appear as a red, itchy rash and spread to areas beyond the sting.
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.
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.
If you notice any shortness of breath, chest or throat tightening, or swelling away from the site of the sting, especially your tongue or lips, call 911 immediately.
The faster they get medical help, the better the chance for recovery. The chances of future total body reactions increase when local reactions become more and more severe. People who are not allergic to bees, wasps, hornets, or yellow jackets usually get better within 1 week.
Delayed reactions are uncommon and occur even days to weeks after the sting. These reactions constitute less than 0.3% of all reactions to insect stings. The individual's own medical history and condition may play a role in determining whether delayed reactions occur.
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.
As long as you're not allergic to bee venom, your immune system will react to the sting by sending fluids there to flush out the melittin, causing swelling and redness. The pain may last several days, but can be soothed with a cold compress or an antihistamine.
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.
These stings will look like a bad mosquito bite, with swelling at the bite site. The area will be red, the center may be white and there may be a small brown stinger still in your skin. A welt may also form.
Antibiotics are not required for most insect bites and stings. In practice, it can be challenging to differentiate between inflammation and infection as both may present with erythema and swelling. Signs of inflammatory or allergic reaction (common) include: rapid onset.
Management of bee or wasp stings
Those with infected bites or stings will need oral antibiotics, usually in addition to oral antihistamines.
Symptoms of a sting
The typical skin reaction includes: Pain: Stings of bees, wasps, and hornets tend to cause pain immediately. Swelling: There may be swelling and redness to the area around the sting. Warmth: The site of the sting may feel warm to the touch.
These observations suggest that after an insect sting, patients may develop delayed-onset allergic symptoms that range from typical anaphylaxis to serum sickness and are mediated by venom-specific IgE. VIT is recommended for patients with these reactions.
Anaphylaxis symptoms usually occur within minutes of exposure to an allergen. Sometimes, however, anaphylaxis can occur a half-hour or longer after exposure. In rare cases, anaphylaxis may be delayed for hours.
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. Pay close attention to your body's responses and even write down what you experience.
The body typically starts to break down histamine within a few hours, which is why the itchiness from a bee sting usually goes away within a day or two. However, in some cases, the body does not break down histamine as quickly. This can cause the itchiness to last for days or even weeks.
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.
