rash on inner thigh

Hi,
I am glad you are not taking this as a triviality… I do not know if you are obese, but obese people often get rashes on their inner thighs, because of rubbing their legs. Ok, this were just a thought. Then second thing is sweating… if having this rash in humid or hot climate, I recommend using powder. Reason for this is sweat rash…
Then again there could be a tone of reasons, really!
Maybe you have genital warts. Hope not, but this is possibility. Then jock itch, which is connected to fungus could be a cause. You must reconsider the options, but most important do not delay, go to your GP and see what it is. Maybe it is nothing, maybe it is something dangerous!
