When skin becomes swollen and hardened after being bitten by a poisonous mosquito, the following measures can be taken:
1. Local cleaning: First, wash the bite area with soapy water or mild saline solution. This helps remove the mosquito's saliva and bacteria, reducing the risk of infection.
2. Cold compress: Gently apply an ice pack or a cold, damp towel to the bite site. This helps constrict blood vessels and reduce swelling and hard lumps. Each cold compress session should last 10–15 minutes.
3. Medication: Under a doctor's guidance, antihistamines such as levocetirizine hydrochloride or loratadine may be used. These medications help control the body's allergic immune response and relieve symptoms of redness, swelling, and induration.
4. Topical treatment: Apply corticosteroid creams such as desonide cream or hydrocortisone butyrate cream. These medications effectively control inflammation and accelerate the resolution of swelling and hardening.
5. Avoid irritation: During treatment, avoid excessive scratching of the bite area to prevent worsening symptoms or secondary infection. Keep the affected area clean and dry to promote healing.
These measures can effectively alleviate skin swelling and hardening caused by bites from poisonous mosquitoes. If symptoms persist or worsen, seek medical attention promptly.
