I don't have any advice about dermatologists/gp's/prescriptions, BUT have you ever tried using coconut oil to help with the symptoms? I had a yeast infection and used coconut oil instead of going to see the Dr. for a prescription and it was wonderful. You can get versions that don't smell coconut-y if you don't want to smell like a beach 24/7 and it has the wonderful side-effect of making your skin baby soft :) Just an option to tide you over until you find a doctor who will help you!
