It sounds uncomfortable to have skin irritation and itching near the vaginal area, especially when it worsens with water contact. This could be due to a fungal infection like vaginal thrush or irritation from other causes.

• You might consider using an antifungal gel such as one containing clotrimazole, which helps treat fungal infections by eliminating the fungus causing irritation.
• Avoid using harsh soaps, scented products, or douching in the affected area, as these can worsen irritation.
• Keep the area clean and dry, and wear loose, breathable cotton underwear to reduce moisture buildup.
• If symptoms persist, worsen, or you notice additional signs like unusual discharge, pain, or swelling, it is important to see a gynecologist for a proper diagnosis and treatment.
• Avoid using any vaginal products or tampons during treatment unless advised by your doctor.
