I'm hoping someone can shed some light on this, as I can't find anything on Google. On and off my son, age 7, gets a terrible rash on his face. It isn't eczema (which he has had in the past.) It flairs up very quickly over a couple of days, and looks like small angry pustules. He says it isn't painful or itchy, but does feel tickly if i gently run my finger over it. Then it scabs over but can take weeks or months to fully disappear. And when it does, it goes very quickly. He had a gastro appointment earlier in the year who linked it to dairy intolerance; it cleared up when we removed dairy from his diet until last week when it came back with a vengeance. It's just on one side of his face now, but in previous flair ups has been on both.
Thank you if you've read this far, hoping for some good ideas.
