Ringworm is a fungal infection caused by a fungal infection that does not heal itself and requires treatment to achieve a cure. If the fungal microscopy is positive then it is tinea cruris and can be treated with oral and topical medications. You can choose itraconazole capsules or terbinafine hydrochloride tablets for oral use and terbinafine hydrochloride ointment, terbinafine hydrochloride spray, naftifine ketoconazole ointment, clotrimazole ointment or luliconazole ointment for topical use. Patients with ringworm should not scrub with salt water, alcohol, vinegar, or use hot water to avoid aggravating the condition. You need to wear cotton, loose, breathable underwear instead of covering it, covering the affected area can cause the rash to worsen.
