I too am very sorry to hear that your daughter is going through this, and as a mom it must be so difficult to watch her suffer.
I continue to have problems with itching, burning etc...I have also tried AD ointment, Desitin, and recently bought Tuck's Medicated Spray (hemhorroid spray) it does burn when initially sprayed, but has provided a lot of relief.
Also, when I was pregnant, during my exam my OBGYN noticed how red and sore my bottom was, and suggested I try Crisco...It was strange keeping a can or crisco in my bathroom, but it worked great!! I try to rotate my products just so I don't get too used to one thing-
hope this helps
