I'm sorry to hear about the swelling and pus coming from your eye. This situation suggests an infection or inflammation that needs prompt medical attention.

Here’s what you should do:

• Avoid touching or rubbing the affected eye to prevent worsening the infection.
• Do not try to self-treat with over-the-counter eye drops without a doctor's advice, as some conditions require specific medications.
• Keep the eye clean by gently wiping away discharge with a clean, damp cloth.
• Seek evaluation by an ophthalmologist (eye specialist) as soon as possible. They can properly diagnose the cause—such as bacterial conjunctivitis, a stye, or another eye infection—and prescribe the appropriate treatment, which may include antibiotic eye drops or other medications.

If you experience worsening pain, vision changes, fever, or the swelling spreads, seek emergency care immediately.

For now, avoid using any eye drops like lubricants unless specifically recommended by your doctor, as they may not address the infection.
