What should I do if it hurts like being pricked by a needle after a mosquito bite?

If you experience pain like being pricked by a needle after a mosquito bite, the following measures can help alleviate symptoms: 1. **Clean and Apply Cold Compress**: Wash the bitten area with running water or mild soap solution to remove any residual mosquito saliva and bacteria. Then, apply an ice pack or a cool, damp cloth gently to the bite to help constrict blood vessels and reduce pain and swelling. 2. **Medication**: If symptoms are severe, you may take antiallergic medications, such as Loratadine tablets or Levocetirizine Hydrochloride tablets, under a doctor's guidance to relieve allergic reactions and pain. Additionally, topical medications such as Calamine lotion or Paeonol ointment can help reduce inflammation, itching, and pain. 3. **Avoid Scratching**: Try to avoid scratching the bitten area to prevent worsening symptoms or causing infection. 4. **Monitor Symptoms and Seek Medical Care**: If the pain persists or worsens, or if signs of infection such as redness, swelling, fever, or pus develop, seek prompt medical attention for professional treatment.
