What are the symptoms after being bitten by mites?

Symptoms after mite bites mainly include the following aspects: 1. Skin itching: When mites bite human skin, they release secretions and metabolites that damage subcutaneous tissue, leading to localized or generalized skin itching. 2. Swelling and rash: Certain components in mite saliva can cause allergic skin reactions, resulting in swelling, red papules, or maculopapular rashes at the bite site. These lesions may vary in shape and sometimes develop into hive-like papules with small vesicles on the top. 3. Blisters and rough skin: In sensitive individuals, mite bites may also cause blisters. Chronic inflammatory responses may lead to skin keratinization, resulting in rough skin. 4. Systemic symptoms: In severe cases, mite bites may cause systemic symptoms such as fatigue, headache, and eyelid edema. These may be related to allergic reactions or infections caused by bacteria entering the body along with mite saliva. 5. Secondary infection: Vigorous scratching of the bitten area may cause epidermal erosion, blood crusts, or secondary infections, further exacerbating symptoms. If the above symptoms occur, it is recommended to seek timely medical attention at a dermatology clinic to avoid self-treatment that may worsen the condition.
