Why is itching
Mosquito when biting, it injects two types of substances into the soft tissues at once: an anticoagulant and an anesthetic. Anticoagulant provides her the opportunity to drink as much blood as possible at a time. Anesthetic substance “masks” the presence of a mosquito on a person, reducing sensitivity. But both of these substances are compounds of proteins foreign to the human body.

The first bite a person does not notice. A mosquito is a very small insect and a small dose of protein in its saliva first passes unnoticed. The fight against proteins begins after a few bites, when enough of them accumulate.
A place mosquito bite inflamed, as with any other damage to the skin with the penetration of infection. Since mosquito saliva causes an allergic reaction, a bite appears at the site of the bite. redness and tissue swelling. Edema in this case looks like a tubercle. However, if a face has been attacked by bloodsuckers, it can eye swell.
If a person does not have an allergic reaction to insect saliva, then itchy lump after bite the case will end. Over time, the body can even adapt to mosquito proteins and stop responding to bites. With allergies, the consequences are much more serious: from blistering to angioedema.

Effects of scratching
Itching after mosquito feeding can be very severe. Sometimes a person scratches an inflamed place mechanically, without even noticing it. But scratching mosquito bites is impossible in any case. The walls of already inflamed cells are very fragile. When combing, they burst, and the poison spreads further. In the case of a weak immune system, such scratching can reach ulcers, and the local small edema will greatly increase in size.
It is impossible for a young child to explain all the harm of combing, and his immunity is still weak. As a result, swelling from the sole combed mosquito bite spread to the whole brush.
But combing not only destroys the cell walls inside the soft tissue. Scraping the inflamed skin, a person damages the upper layer of the epidermis and causes an external infection in the wounds. Against the background of such problems, the spots and scars that remain after scratching seem to be a minor cosmetic defect.
