Hi All; about 3 weeks ago my son seemed to spontaneously develop a rash under his nose. It is red and blotchy and occasionally has a tiny white bump or two. I did some googling and think it may be peri oral dermatitis, but I really don't know for sure. We haven't used any different lotions, foods, etc, to bring it on, so I'm at a loss as to how he got it. I was treating it at home with OTC anti fungal creams, antibiotic creams, and also tea tree oil. Some days it looked like it was clearing up, only to look worse later. This morning I noticed a red blotch closer to his mouth, so it appears to be spreading. I am going to make a dr appt, but in the meantime, am wondering if anyone else has encountered anything like this. Thanks!
