What should I do if I get red bumps on my body from insect bites?

When red bumps appear on the skin due to insect bites, the following measures can be taken: 1. **Clean and Apply Cold Compress**: Clean the bite area with clean water or soapy water to prevent infection. Then, apply a cold compress, such as an ice pack or cold towel, to the bump to help reduce swelling and itching. 2. **Topical Medications**: Apply an appropriate amount of antiallergic or anti-inflammatory ointment, such as mometasone furoate cream or desonide cream. These medications can help alleviate inflammation and relieve itching. 3. **Oral Medications**: If symptoms are severe or topical treatments are ineffective, oral antihistamines such as levocetirizine hydrochloride tablets or loratadine tablets may be taken under a doctor's guidance to reduce allergic reactions. 4. **Avoid Scratching**: Although the affected area may itch, avoid scratching to prevent worsening symptoms or causing infection. 5. **Seek Medical Attention**: If the red bump persists or is accompanied by systemic symptoms such as fever or nausea, it is advisable to seek timely medical evaluation for professional diagnosis and treatment.
