What it looks like:
Sudden, soft swelling (may be itchy)
Possible redness or mild warmth
Often improves within 24–48 hours
Why it happens: Histamine response to bite or irritant.

What it is: A bacterial infection of the eyelid skin and soft tissues in front of the eye socket.
What it looks like:
Diffuse redness, warmth, and swelling of the eyelid

🚩 When to Contact a Healthcare Provider
While most eyelid lumps are benign, certain signs warrant professional evaluation:
✅ Call your pediatrician or eye doctor if:
The lump is rapidly growing, very painful, or spreading redness
Your child has fever, vision changes, or eye pain
The eye itself is red, bulging, or difficult to move
