Hi, thanks for posting your query.
You have small red raised rashes with itching more at night. They heal and show up in other areas. Econazole
nitrate is an anti fungal cream. Your doctor has treated you for a fungal infection
The other possibility can be urticaria
or Bug bites.
Since you are not benefited with this cream, you may report to your doctor.
He may re look into the diagnosis give you appropriate treatment.
Till then you may take oral anti histamine
like levocetrizine for itching twice a day and local application of calamine
Hope this solves your query.
