Hello
Thanks for posting your query at DoctorSpring.com
I can understand your concern.
She has an eczema called nummular dermatitis.
Application of cortisone cream twice a day on the affected area should help resolve it.
In case it doesnt help, its best to get a prescription from your doctor for mometasone cream which can then be applied once daily.
Please let me know if you have any queries.
Take care
