Thanks for posting your query at DoctorSpring.com
I can understand your concern.
This seems to be eczema. She needs to apply mild topical steroid cream like cortisone once daily for a week and see if that helps. also she can apply elidel cream twice a day on the affected areas.
That should help in resolving the eczema but since eczema is a tendency that you have in your body, it cant be rid of , but it can be kept in check.
Please let me know if you have any queries.
