My granddaughter developed a rash on her right shoulder and buttock area. At times, the area will look better. It seems to move. Right now, it is more prominent on her chest and under the arm. We have been using oral steroids and hydrocortisone on the skin as prescribed by the doctor. This did not clear it up. It reappeared yesterday. Sometimes, it appears as a fine rash, then at other times, it is more red with an inflamed appearance. Around August 7th, she had the MMR with chickenpox vaccine. They went to the beach around the middle of August. She played in the sand at the beach and got into the pool at the resort. They thought it may be a carseat they had gotten previous to the beach trip that had the flame retardant finish on it. They changed it out, keep her home for two days. Today, the rash reoccurred.
