I'm trying to figure out what she has. I don't know if it is a sickness or a allergic reaction or something. She is 4 years old and her symptoms are swelling, pain, and redness. She has swelling on her feet which she says hurts, some swelling on her lower body(bottom and stomach region). She has some swelling red areas on her arms. At first she said this was itchy and then said it hurt and it was swelling. Her legs are a little swollen too. I really don't know what this is, and I tried calling a doctor and they were closed. If you could tell me what this sounds like I'll really appreciate it.
