### Patient: Doctor, I have a red and swollen bump on my eyelid, and it's causing me a lot of pain. There's also some abnormal appearing skin around it. Can you tell me what's happening?
### Doctor: Based on your symptoms, it sounds like you have a stye. It's a common infection of an oil gland on the eyelid that causes redness, swelling, and pain. We can treat it with warm compresses and sometimes antibiotics if necessary.
