Hi Thanks for writing to HCM. Scabies is a mite infestation
where there is severe itching
at night .It usually affects flexural areas of body like underarms,genitalia etc.Other members of family are also affected.Since your child has itching in extensor aspects of body like elbow,wrists it is possible that he may suffering from atopic eczema
.Treatment for both differs and it will be better you consult a dermatologist
.Use mild soaps like dove,apply plenty of emollient
after bath.Use loose cotton clothes covering whole body.You can continue with hydrocortisone
but apply it only for few days (up to 1 week).
