Same here it just came out of nowhere it happened to me months ago. I had taken many showers to see if it come of but it didn't and it stings.When I'm in the water at the beach and the shower it is like a burning sensation, and when I sit down I feel uncomfortable.
I have the EXACT same symptoms. I am way too embarrassed to see a doctore about it because it is so flakey, and I have huge scarring from scratching so much. Im so depressed about it because it has ruined my body. I will never be able to wear a bikini bottom in summer because the scarring is terrible :(
Hello,
I cannot confirm anything without examination but it sounds like a fungal infection. Wash your groin daily and then dry thoroughly by pat drying,not rubbing. A hairdryer is useful if you have hairy groins.The damp groin is an ideal site for fungi to multiply.Also wear cotton underwears and change them twice a day. and do not share other people’s towels.Application of local antifungal cream(terbinafine, clotrimazole, econazole, ketoconazole, miconazole) and oral antifungal drugs are the mainstay of treatment.
I hope that helps. Take care and please do keep me posted on how you are doing or if you have any additional doubts. Kind regards.
