Hi, I can understand your concern for recurring tinea. I am providing you certain suggestions for the betterment which are applicable for the condition: - Keep your self away from hot and humid climate. - Take two times bath. - Wear cotton clothes and cotton undergarments to be changed two times a day. Do not wear any synthetic or tight garments. - Do cold compression or warm water compresses according to the weather condition. - Do not sit continuously for long hours. Do all the measures to prevent sweating at this area. -If I were your treating dermatologist then would have suggested to apply an anti-fungal creams such as Sertaconazole or clotrimazole . -I would have preferred to give an oral anti histamine like loratadine two times a day if there is moderate to severe itching is present. -Don t try to scratch or rub the area as can lead to further aggravation of the problem. - You can use any good antiperspirant powders daily to avoid future infection. - Reduce your weight if it is on higher side. All the best.
