question: Hi doctor,I am suffering from jock itch for two months. Initially, there were well-circumscribed lesions with darker edges and itching on groin folds. Now, the skin has become hard, pigmented and dry with loss of hair. Scrotum and penile shaft also affected and resulted in the loss of rugosities and hair as well. Earlier I used Ketoconazole cream 2%, and now I am on Terbinafine cream 1%.
