Suggest Treatment For Itchy Scrotum

Hi Dr. Rynne, I have been diagnosed with Lichen by a dermatologist, I tried some homeopathic remedies he gave me but it hasn t really killed the problem. I have an itchy scrotum which wakes me up usually early mornings. In the day it doesn t bother me at all. Moment I change into my night suit, to watch some television I tend to start scratching, specially in the summers. In the winters, its just early mornings which see me getting up earlier than normal scratching, every now and then. Look forward to any advice you can give me. Thanks.
