What Causes Itching Between Buttocks?

I have a very itchy butt crack and I have scratched it to the point where it bleeds and the skin flakes off in chunks. I had a hysterectomy and I have major hot flashes and I sweat a lot and I blame it on that but it is getting worse instead of better and I see a tiny rash but I don t know if it is from scratching or not

Dermatologist 's  Response
Hello. Thank you for writing to us at healthcaremagic

I suggest a possibility of Fungal Infection/Tinea cruris. Chaffing and itching are suggestive of fungal infection
Body folds being a common site for fungal infections because they provide an ideal environment for the fungus to proliferate which grows well in moist and warm condition.
A KOH wet preparation made from scraping a small amount of scale from the surface of skin lesions to look for fungal elements would be confirmatory of fungal infection.
If KOH scraping is positive for fungal elements I would suggest you to apply a topical antifungal.
Either an OTC topical antifungal e.g clotrimazole 1% cream can be tried or one of the prescription antifungals like sertaconazole, luliconazole, bifonazole etc. Thye need to be used twice daily for 4 weeks.
An OTC oral antihistamine e.g cetrizine 10 mg once daily will provide you symptomatic relief from itching.

Regards
