My DD will be 4 in September and on Tuesday she came down with a fever and on Wednesday morning woke up with a rash. Rash is spreading from upper arms to lower arms and hands, from upper legs to lower legs, from face to neck from upper back to lower back. Fever continues. SHe also has swollen lips, eyelids and cheeks and is congested. This really looks like measles. What do I do to help her feel better and make sure that she doesn't have any complications?
