My four year old daughter has suddenly developed swelling around her eyes, nose and cheeks.. Eyes and cheeks are mildly red and doesnt seem to hurt. The skin has small bumps. No obvious bites, wounds or throat swelling.. No circumstances have changed recently to make me think allergic reaction, and shes never had an allergic reaction to anything. She recently got over a mild feverless cold with congestion and runny nose.. Any ideas?
