my 8 year old son has a red,scaly ringworm type circle in his groin area. There is what appears to be possible heatrash above the reddness. three or four circles under the rash, and a few more in spots the his hip,he also says there is no pain or itching.The red spot looks like a blister type has popped and the scaly shin is trying to heal,this has only been 24 or so hours.I feel i need to put a cream lotin on it,just not sure.he is very allergic to poision ivy,and this doesnt seem to spread,that i can tell. i just dont know if he should see a doctor. if its contagious i need to take those precautions,as well. what to do? thNKS
