Why is it so painful to be nailed by mosquitoes, it still feels itchy, and it will swell!

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.

Mosquito bites will itch after biting, because mosquitoes will secrete saliva at the same time when absorbing human blood, and this saliva is an anticoagulant, anticoagulant not only plays a role in preventing blood clotting, the formic acid in it will also cause local allergies at the bite site, which will lead to itching, if the mosquito contains toxins, it will also cause insect bite dermatitis, and even bacterial and viral infections.

After being bitten by mosquitoes, first remember not to scratch, the scratching process will damage the tissue, scratching will cause infection. Because itching is caused by an allergic reaction to formic acid or other toxins, eliminating the allergic reaction and removing the toxins can stop itching.
