What is the red mark, not a mosquito bite, itchy?

This red mark on your body may be hives, also known as hives from allergies. Hives from allergies can be itchy. If you are sure that it is hives, you can take some oral medications such as cetirizine hydrochloride oral liquid.

or cetirizine hydrochloride tablets. Calamine lotion can be applied to the outside.

It should be an allergic reaction caused by clothes, bedding, etc. I used to encounter it when I was working part-time, and I didn't know what was going on at first, but I saw a few doctors, some said this, some said that, and the medicine didn't work, and the smear medicine I bought could only temporarily relieve the itching. Later, I found out that it was caused by the futon I bought, and the symptoms gradually disappeared after changing the futon.

The red mark on your ** belongs to the ** problem, or it is an allergic problem, I hope you go to the hospital** department for a check-up, do not delay.

It may be bitten by lice and bed bugs, it may be caused by mites, it may also be rheumatism, or it is allergies. FYI!

If there is this place, it is simply the mark of mosquito bites, some people consume fast and some are slow, go to the pharmacy to buy mosquito bite ointment to apply, if there is a whole body, accompanied by other symptoms, you have to go to the hospital to diagnose what the disease is.

If you don't have a mosquito bite, see if there are bed bugs or other bloodsucking insects in your home, if not, you may be allergic to a certain substance or moisture, etc., so you should go to the hospital for a checkup.

If it is flat, slightly higher than **, and itchy, it may be hives, caused by allergies, such as allergies to cold air, allergies to certain foods.

You should see a doctor.

Itchy, rub it with fake wine or wet it with water, and then rub it with a gypsum surface (used to make tofu) to see the effect.

Allergies, see a doctor in a tertiary hospital!

Check your immune system.

Instead of "biting" us, mosquitoes pierce their long "straw"-like mouthparts into the veins under us, and then suck our blood, just like we drink a drink. The reason why we feel itchy is because mosquitoes suck blood at the same time, in order to prevent blood clotting, they spit some saliva in our **, these saliva carry mosquito venom, and most of them are acidic, and soapy water can neutralize the acidic substances of mosquito saliva, which is why after being bitten by mosquitoes, you can use soapy water to wash the affected area.

As for the redness, it's not all mosquitoes to blame, it's our body's immune system that reacts when it perceives an intruder. Our body treats the mosquito bite as a wound, so it transmits an amino acid produced by protein breakdown to there, and under the action of this amino acid, our microblood vessels will dilate, and at the same time, white blood cells, lymph, etc. will gather together, resulting in redness and swelling.

Even in the crisp autumn season, don't forget to prevent mosquitoes, especially when you go out for an outing, you must remember to bring flower water, after all, the "mosquitoes" in the wild are very "hungry", in addition to these, what else do you need to pay attention to in life to prevent mosquito bites?

1.Clean up stagnant water in a timely manner. Water is an important growth condition for mosquitoes, and the stagnant water should be cleaned up in time to prevent mosquito breeding.

2.Use insect repellent tools. Priority is given to the use of safer physical methods such as mosquito nets, mosquito swatters, and mosquito trap lamps, followed by mosquito coils, aerosols, etc.

3.Spray insecticides with dark and damp conditions. Mosquitoes prefer to hide in dark and damp places, and can spray insecticides on the corners of the house, ceilings, under beds, table legs, stairwells, sinks, etc.

4.Place wind oil essence in the home or plant mosquito repellent plants.

If you are bitten by a mosquito and have other serious reactions such as high fever, you must seek medical attention in time.
