I'm sorry to hear about the painful wound from the insect bite on your neck. Here's what you can do to care for it:

• Clean the area gently with mild soap and water to prevent infection.
• Avoid scratching or rubbing the wound to reduce irritation.
• You may apply a topical corticosteroid cream like Lycor 1% Cream, which contains hydrocortisone. This can help reduce swelling, redness, itching, and pain. Use it exactly as prescribed by a doctor.
• Keep the area dry and uncovered unless advised otherwise.
• Watch for signs of infection such as increased redness, warmth, swelling, pus, or fever.

If the pain worsens, the wound shows signs of infection, or you experience other symptoms like fever or spreading redness, please consult a dermatologist promptly.

For now, avoid using any creams without medical advice, especially if you have allergies or sensitive skin. If you are pregnant or breastfeeding, consult a doctor before using any medication.

If you notice any severe allergic reactions like difficulty breathing, swelling of the face or throat, seek emergency medical help immediately by calling Apollo Emergency at 1066.

Taking these steps can help your wound heal safely.
