Why do some mosquitoes still itch for days after being bitten???

Because the text here is more rampant, it is mutated, and there are few trees here, and it is relatively empty, so there are more mosquitoes.

When our body's immune system is injected with anticoagulant fluid and other pathogens from a bite, it releases a protein called histamine to fight foreign substances, and this immune response triggers an allergic reaction at the bite site. Histamine causes swelling of the tissues around the bite as blood flows to the bite site to speed up tissue recovery, and the intensity of this allergic reaction varies from person to person, with some people reacting severely to allergies.

Almost everyone has the unpleasant feeling of being "bitten" by mosquitoes, in fact, it should be said that they are "stung" by mosquitoes. Mosquitoes can't open their mouths, so they won't bite on the **, it actually uses 6 needle-like structures to pierce people**, these short needles are the center of the mosquito's edible mouthparts.

These short needles suck human blood in the same way that they draw blood; The mosquito also releases saliva containing anticoagulants to prevent blood from clotting, so that it can feast peacefully. When the mosquitoes are full of food and drink and float away, all they leave behind is an itchy lump.

However, the itchy sensation is not caused by a short needle pricking or chemicals in the saliva. We feel itchy because the body's immune system releases a protein called histamine to fight foreign substances, and this immune response triggers an allergic reaction at the bite site. Histamine causes swelling of the tissues around the bite when blood flows to the bite site to speed up tissue recovery, and the intensity of this allergic reaction varies from person to person, with some people having a more severe allergic reaction to a mosquito bite.

Only female mosquitoes bite mammals because they have to suck blood every three or four days to get the protein they need to make eggs; Male mosquitoes mainly feed on nectar, while female mosquitoes use animal body heat and physiological changes to search for targets, which may be why human ankles and feet are more commonly bitten by mosquitoes, because the blood vessels in these parts are closer to the body surface, so more body heat is released.

In terms of mosquito species, there are more than 200 species of mosquitoes in the United States and more than 2,500 species worldwide. In fact, mosquitoes can be found everywhere except Antarctica, and they can also transmit diseases such as malaria, yellow fever, encephalitis, and West Nile virus, and more than 700 million people are infected by mosquitoes every year.

First, it's best to use less soap in the bath. Generally speaking, mosquitoes like to eat nectar dew, so the probability of being bitten by mosquitoes increases after using perfumes, cosmetics, creams, and other items with a floral scent. However, not all scents will provoke mosquitoes, such as the cologne commonly used by men because of the sandalwood scent, which can play a role in repelling mosquitoes.

Second, eat more vegetables. Some vegetables contain odors that mosquitoes don't like, such as carotene-containing vegetables and spicy vegetables such as garlic, which will keep mosquitoes away from you after people eat them.

Third, wear light-colored clothing. Aedes mosquitoes, also known as Aedes versiflora, prefer to rest on black clothing.

Fourth, try to wear socks as much as possible. Many girls like to wear shoes barefoot, but after wearing socks, mosquitoes feel that people's **humidity decreases, and volatiles on the skin surface decrease, which will reduce bites.

Fifth, you can't scratch after being bitten. After scratching, the tissue fluid, lymph and other fluids in the ** ooze out and swell into a bag, which will become more and more itchy, and it is not easy to subside, and the "red bean legs" covered with red envelopes are scratched out in this way. If you insist on not scratching, the itching will subside significantly after 10 to 15 minutes.

Hello, your symptoms belong to allergic urticaria.

Urticaria is manifested as a wheal, localized flat bulge of varying size, as small as a broad bean and as large as a palm, or it can be fused into patches, such as a map or ring. Appear in batches and disappear from time to time, leaving no trace after subsidence. As you said, like a mosquito bite, the wheal can sometimes be itchy and stinging.

I'm from the past, and I've been suffering from hives and swelling and pain in my mouth. Rest assured, the swollen mouth will subside over time and will return to its previous appearance.

In addition, the appearance of hives can lead to bright red, reddish or porcelain-white wheals of varying sizes on the skin, which can lead to other conditions if not treated in time**. So I suggest you go to the hospital for a check-up, I have also suffered from hives and can understand your feelings.

During this period, please do not eat fish, eggs, seafood, beef, etc., the reason why you can't eat them is because these foods are the most likely to trigger the onset of hives, please do not eat these things until you know the source of the allergy.

I used to take a lot of medicine, saw a lot of doctors, and I was ** as soon as I finished eating, and I can understand the fear of being anxious and painful.

So I recommend that you go to the hospital to check the source of your allergy so that you know what you should not eat, including other foods that contain this stuff, so as to avoid another recurrence of hives.

Note: Some urticaria is more sudden, if it is not timely, it will be more troublesome and will cause other diseases, so do not delay, go to the hospital for examination as soon as possible.

If you still have any questions, you can feel free to ask me, I hope you can ** as soon as possible.

It means that the toxin has not been eliminated, and I used to be like that.

Apply a little iodophor disinfectant, the effect is better, wipe it once in a few hours, and it will be fine in two days.

I once didn't know what to bite, according to the usual habit, apply a little soap, wipe a few times will have a noticeable effect, a day later.

But that time it didn't work, and it didn't work for two days. I found out that I had iodophor disinfectant at home, so I tried to apply a little bit of it, and it quickly worked. So I continued to wipe it, and it was fine after two days.

It's normal, I often do this, if you don't feel at ease, go to the hospital for a check-up.
