My 2 sons have a red bumpy rash over their, face, arms and legs.  Some of the rash has joined together.  They both have a slight fever and have had flu like symptons.  My youngest keeps complaining of a sharp pain in his head that keeps coming and going.  They are 9 and 6 and generally well
Hello, I read carefully your query and understand your concern. The symptoms seem to be related to a viral rash. I suggest using Tylenol for the flu like symptoms. I also suggest using Calamine lotion for local application. Hope my answer was helpful. If you have further queries feel free to contact me again. Kind regards!  Chat Doctor.
