What causes a swollen under-eye and pain when touched?

Hello,

Welcome to icliniq.com.

I can understand your concern.

It sounds uncomfortable and concerning to have your undereye suddenly get sore, swollen, and painful when you blink, especially after that sharp pain you felt earlier. When something like this happens to your eye, it is natural to feel worried. From your description, it could be a few things:

Possible causes of your eye discomfort -

1. Infection around the eye (cellulitis): This is a common concern. It might be an infection of the eyelid and skin around your eye, even if there is no redness right now. If the infection is deeper, it could affect how your eye moves, making blinking painful.

2. Stye or chalazion: These are issues with the oil glands in your eyelid. A stye is usually a painful, red bump, while a chalazion is a blockage that causes swelling and tenderness. Either could explain the pain when you blink and the soreness.

3. Tear sac infection (dacryocystitis): An infection in your tear duct area, near your nose, can cause swelling that spreads under your eye and makes blinking hurt.

4. Sinus issues: Given that the pain started in your cheekbone area, it is possible that inflammation or an infection in your sinuses could be causing referred pain and swelling around your eye.

Why it is important to get it checked out -

Because your eye is involved and it hurts to blink, it is really important to get this looked at by a doctor soon. Eye infections can sometimes get worse quickly, and a healthcare professional can figure out exactly what is going on and get you the right treatment to feel better. They might need to do an eye exam or even check your sinuses.

Do not hesitate to reach out to your doctor or an eye specialist (ophthalmologist) to get some peace of mind and proper care.

I hope this information will help you.

Kindly follow up if you have more concerns.

Thank you.
