DD is 14 months and has had severe nappy rash for c. 6 weeks. Was diagnosed as fungal and we have so far had Miconazole and Hydrocortisone from GP and now we're 5 days into a 7 day course of Ketaconazole, but it keeps coming back. DD gets v uncomfortable and the other evening couldn't sit down properly and screamed for 30 minutes, before we realised what it was. Anyone had this? Would really appreciate advice/reassurance.
