DD has got this rash behind her knees which is very strange. At first glance it looks just like eczema but to touch it's is a patch of hard little lumps. If I squeeze one white stuff, rather like dried pus comes out. They're not blisters, rather like rock solid white heads that haven't quite reached a head IYKWIM.
Any idea what this could be and how to put an end to it. I've tried a range of steroid, antibiotic, antibacterial and anti-fungal creams to no avail.
