The swelling and redness from your insect bite improving by day 3 is a good sign, but you can take some steps to ease discomfort and support healing.

🩺 Relief Measures

• Clean the area gently with mild soap and water to prevent infection.
• Apply a cold compress or ice pack wrapped in cloth for 10-15 minutes to reduce swelling and pain.
• Use a topical antibiotic cream like one containing sodium fusidate (e.g., Chitomesh Sugar Free Cream) if there are signs of infection or if advised by a doctor.
• Avoid scratching or irritating the bite to prevent worsening.
• Over-the-counter antihistamines or pain relievers can help with itching and pain if needed.

⚠️ When to See a Doctor

• If redness, swelling, or pain worsens or spreads after day 3.
• If you develop fever, pus, or other signs of infection.
• If you experience difficulty breathing, dizziness, or severe allergic reactions.
