Turns purple after being bitten by an insect

As we all know, mosquitoes like to bite people and suck human blood. The venom in the mosquito's body will cause people to have small blisters and feel very itchy. This is the most painful thing, but people often have no way to deal with small mosquitoes. Everyone reacts differently to mosquito venom. Some people react seriously, while others react less seriously. This is also related to the mosquito itself. So what should you do if your skin turns purple after being bitten by a mosquito?

Consider the symptoms caused by insect bite dermatitis. You can apply Wuji ointment and calamine lotion for local treatment to avoid scratching and prevent infection. It is recommended to eat a light and easily digestible diet, drink plenty of water, enhance the body's metabolic function, and avoid spicy and irritating foods and seafood. This situation is considered to be caused by redness and swelling of the tissue after mosquito bites, and some symptoms of subcutaneous congestion after local blood vessels are affected. It is recommended to go to the hospital for a check-up and a clear diagnosis. Depending on the specific situation, you can apply cold compresses to relieve the symptoms. At the same time, take some anti-inflammatory drugs to prevent infection. Generally, it can be absorbed by itself and no special treatment is required.

At the beginning, you should seek treatment immediately, buy antihistamine allergy medicine and take it for a period of time, gradually reducing the dosage over time. Also, take a bath with topical lotion, clean the bitten area with alkaline soap, and then apply ointment for mosquito bites. Some people with weak constitutions should try to avoid bites. If the insect bite dermatitis does not heal within half a year, go to the hospital for treatment and care as soon as possible, and cure it as soon as possible, otherwise it is easy to form an itchy rash. If the area around the wound turns purple, it means that there are toxins such as thrombin. It is recommended that you rinse the wound in time to avoid the growth of anaerobic bacteria, observe the wound promptly and provide symptomatic treatment. If necessary, you need to conduct regular blood and urine tests, liver function tests, etc.

This situation is probably an allergy caused by mosquito bites, because scratching and squeezing cause allergic dermatitis. It is recommended not to squeeze after being bitten. You can apply iodine tincture or green ointment externally to avoid the spread of toxins. Slowly, it will return to normal. The more irritated, the more obvious the swelling will be. Insect bite dermatitis, also known as "papular urticaria", is mainly related to the bites of arthropods, such as mites, and is more common in spring, summer and autumn. Different insect species and body reactivity can cause different skin reactions at the bite site. It is generally a red edematous papule with small blisters in the center, the size of soybeans, and is more common in exposed areas and around the waist. Treatment can be done by applying compound anti-inflammatory cream or Wuji ointment externally and taking antihistamines orally.
