My 10 year-old daughter was seen earlier by our pediatrician. She was ill last week with fever, sore throat, and diarrhea. She appeared to recover and we returned her to school. The strep test she received is negative, but she continues to be getting worse. She now has newer symptoms of weakness in her hands; and says they feel funny. She also feels heavy. She does not look well and it even appears that there is some swelling in her face. I m concerned.
