Hi, I have a rash on my groin area in the cracks of my legs it looks somewhat like jock itch but it doesnt have red bumps. It has made my skin dark dark brown when I on the other hand am pasty white...when i first got the rash the edge of it was distictive in a way the rash itself was brown and the edge was very very dry white flakes now after months and months of trying every cream it is still not leaving me. Now the rash is all dry but still brown underneath. It has gotten so bad that i have literally itched my skin down to nothing. I went to the dermatologist and he decided to look at the rash ontop of my rash (a yeast rash that wasnt bothering me at all and has also healed) I have no idea what to do but i cannot keep itching like this. even as i type this i feel the itch crawling back.

Hello and welcome to Chat Doctor Fungal infection of the groin/jock itch develops due to conducive environment provided by the body folds. Sweating, humidity, obesity are factors that encourage fungal growth. Regarding pigmentation in the groins, it is most likely post-inflammatory hyperpigmentation secondary to recurrent fungal infections which you experienced in the past. Pigmentation would lighten by itself gradually if the fungal infections are not allowed to recur. Since fungal infections can recur again due to favorable condition for fungal growth, therefore you need to use an antifungal dusting powder in the folds regularly which will not only keep the area Chat Doctor. -I would normally advise my patients an oral antifungal (fluconazole 150 mg once every week for 6 weeks).-I also advice in my patients, a topical steroid+antifungal combination cream (clotrimazole+Beclomethasone) twice daily for 4-6 weeks.-An OTC antihistamine like cetirizine once daily in the evening will help you with the itch part-Once my patients are cured(usually 4-6 weeks) I ask them to use an antifungal dusting powder (clotrimazole dusting powder) in the folds, to prevent recurrence.
