Close shaving may cause minor abrasions or injuries at the skin or epithelium. This provides an easy access to fungal or bacterial infection at that area. Apply some antifungal or antibiotic ointment at your genital area twice daily under your gynecologist s guidance. Keep the area clean and moisture free. Take some oral antihistaminics like Cetrizine or chlorpheniramine twice daily to reduce itch. Dont scratch when you feel itch instead apply warmth through fomentation. Never shave close and without softening the hairs. Soften the hairs with some shaving cream or soup. This will prevent minor abrasions. Hope this will you.
