Have you tried antihistamines, both topically and in tablet form? If the itching is an allergic reaction they might help.

If, however it is like an eczema, then you probably want a stronger steroid cream, like Diprosalic or Synalar-C. Those are UK names and they are prescription only over here.

Ask the quack again.

The juice of an aloe vera plant might well help but probably not for long at a time.
