I had a hysterectomy 3 years ago and since then I have been itchy between my legs... no blisters, rash or scales. just itchy. its all external. i feel the need to keep powder between my butt cheeks.. one dr. told me it was a yeast infection but I know for a fact it is not that. My husband does not have any issues. so I feel like its not anything contagious. I feel like my ph is off balance and im too acidic? please help.
