A rash in the groin area that has lasted for a year and keeps returning after stopping creams is most commonly due to a fungal infection that has become persistent or has been partially suppressed by steroid-containing creams. Creams such as Neo-Clobenate GM often contain a steroid along with antifungal and antibiotic medicines. While steroids may temporarily reduce redness and itching, they can also weaken the skin and allow the fungal infection to spread deeper or return more severely once the cream is stopped. The itching, pain while walking, foul smell, and oily discharge suggest that the skin may now be irritated, infected, or damaged from continuous friction and moisture. It is important to stop using mixed steroid creams without a dermatologist's advice and get properly examined by a skin specialist. Treatment usually involves a full course of antifungal medicine, either as a cream or tablets, depending on the severity, along with strict hygiene measures. Keep the area clean and completely dry, wear loose cotton underwear, avoid tight jeans, change sweaty clothes quickly, and dry the groin properly after bathing. Do not scratch the rash, and avoid sharing towels or clothing with others. If you are overweight, diabetic, or sweat excessively, managing these factors can also help prevent recurrence. Since the rash has been present for a long time and is causing discharge and pain, a dermatologist may need to examine the skin closely and sometimes perform tests to confirm whether there is fungal infection, bacterial infection, eczema, or another skin condition. With the right treatment and regular care, most chronic groin rashes can improve significantly.
