Sadly, that is the kind of medical care I have come to expect.
I would ask if maybe it might be dietary/ allergy related. I say this because all my kids have allergies an intolerances (we are still on waiting lists for the specialists to find out what for specifically) and they present with skin rashes that are completely untreatable. Chantelle currently has it on her cheeks, but also gets it as a nappy rash too. But it isn't a real nappy rash, it is when whatever she is reacting to is touching her skin on the way out. We have no idea what is causing it. We do know it is from some kind of allergy / intolerance though. And because my kids seem to react to 'basic' foods, an each of them different foods trying an elimination diet for them is all but impossible (ir, Nate cannt have more then a tiny bit of dairy, only certain types of bread, only one peice of fruit a day, etc; whereas Angel can eat all of that stuff but cannt have cheap tomato sauce (only Heinz in small quantities) and no other sauces - we believe her problem is a specific preservative, but no idea which one).

One thing we find with Chantelles nappy rash is that it is usually best to avoid the anti fungal creams and zinc and barrier creams, and just use savlon antisceptic (to prevent infection of the sores) until her body has a chance to sort itself out. Don't use the other types of anticeptic cream though, they sting.
