It could be an allergy or a virus. It's best to get it checked out.
Ya i have an appt tomorow hopefully will be good news
If the allergy was from milk, the allergy will be systemic. Meaning the rashes will spread fast to the whole body, beginning with the itching of the eyes, nose, throat and then the rashes. However, if it is only localized to one part of his body, it could be a skin rash as a reaction to something, such as his perspiration mixing with the soap used to wash his shirt. Best to have it checked.
Ya i had it checked he said could just be a heat rash 2 differnt doctors but yet its still there:( maybe im freaking out for no reason
