Earlier today my 4 year old threwup and I noticed a rash on his chin. He has been running a slight fever (around 100) for 2 days now. The rash has not spread on his face,however, tonight when i went to give him his bath i noticed a small rash on his back and stomach (not really very noticable) and then I noticed that his penis and balls were swollen and red. They too have a rash. He has been scratching there all day but I just figured his underware were bothering him. Upon touching the rash on his face my hand instantly began to itch (could just have been the thought of his itch I guess). Now I have a slight rash on my neck and arm. I have sensitive skin and get hives easy. Any clue what the rash might be? He hasn't ate anything different, we are using the same detergent and we don't use bubblebath. He has had yeast infections in the past but not since becoming pottytrained. I am trying to remember if he used his brothers towel after his last bath but can't remember but is it possible that if he did use his brothers towel he got an infection from him because his 2 year old brother has a yeast infection that I am currently treating.
