my lilttle brother is almost 2 years old and on Friday he went ot the doctor for four shots.. The doctor said it would be normal for him to get a little rash .. He just woke up from a nap and he has a huge rash and the outside of it is white and hard, some areas are more white then others ... he seems to be itching it too. My mom called the doctor and there is no one in the office.. Should she take him to the ER? Thanks
