My 3 year old daughter developed a red blistery rash on her cheeks, nose, arms, chest, stomach, back, bum, legs and feet on Thursday night. The rash comes and goes. It is very itchy. Her hands and feet are swollen when the rash appears. She also has a cough and a runny nose. She is sleeping a lot more. Benydrl doesnt seem to be helping at all. I have taken her to 2 different doctors and no one can seem to give me an answer about whats going on.
