I am a 29-year-old woman, 5'4'' tall and weigh 70 kg. Two years ago, during summers, I got ring-like rashes near my arm-pits, under breasts and in inner thighs. They were dark-brown in colour and would cause a lot of itching. Assuming that it is a fungal infection, i applied a known anti-fungal cream 'Ringuard'. Though the itching subsided, the rashes still remained. As the winters came almost all disappeared but those in inner thighs gave way to a dark discoloration. Now this year too, these have recurred but only in inner thighs. I have been more careful this year, i.e., I have started taking bath before sleeping, drying the groin well and changing undergarments twice a day but that hasn't help much. The rashes are still there and it looks very ugly. I am fair but the skin in inner thighs has darkened a lot. Can this be cured?
And how can the recurrence be avoided? As i am a little overweight, is it possible that the skin is darkening because of the friction between skin? Please help.
