why do wasp stings swell so much
The majority of people without sting allergies will show
only minor symptoms during and after a wasp sting. The initial sensations can include sharp pain or burning at the sting site. Redness, swelling, and itching can occur as well. YouБre likely to develop a raised welt around the sting site. A tiny white mark may be visible in the middle of the welt where the stinger punctured your skin. Usually, the pain and swelling recedes within several hours of being stung. БLarge local reactionsБ is a term used to describe more pronounced symptoms associated with a wasp or bee sting.
People who have large local reactions may be allergic to wasp stings, but donБt experience life-threatening symptoms, such as anaphylactic shock. Large local reactions to wasp stings include extreme redness and swelling that increase for two or three days after the sting. Most of the time, large local reactions subside on their own over the course of a week or so. Let your doctor know if you have a large local reaction after a wasp sting.
They may direct you to take an over-the-counter medication (such as Benadryl) to reduce your discomfort. Having a large local reaction after a wasp sting one time doesnБt necessarily mean youБll react to future stings in the same way. You could have one strong reaction and never show the same symptoms again. On the other hand, a large local reaction could be the way your body routinely responds to wasp stings. Try to avoid being stung to prevent these uncomfortable symptoms.
A wasp's sting isn't the sort of thing most people take for granted, but the same can't be said for the chemical makeup of the venom. After all, why does a wasp sting hurt so much? To get to the bottom of wasp venom, it's important to understand exactly what pain is: localized physical suffering associated with physical injury or disease. Basically, it's the nerves telling the, Hey, your arm is damaged, or Move, your leg is on fire. The intended result is that the creature experiencing the pain will fight or flee, whichever best removes the threat of more physical damage.
For more information, read. With wasp venom, the pain, which can be very intense, is an exaggeration of the actual physical damage, which is minimal. The sting enables the wasp to convince larger threats that it's capable of dishing out far more physical damage than one would expect from a creature so small. The message, often driven home with bright body coloration, is leave us alone.
Wasp venom achieves this effect by waging a staged attack against the nervous system on a level. This sting accomplishes the goal of persuading most large animals not to try to kill or eat the wasp. Think of pain as a security system, only for your body. A wasp sting might not actually burn the house down, but it sure can set off all the and sprinkler systems. But there's much worse in store for the smaller victims of wasp stings -- the gory details of which we'll explore in the next section.
