What Make My Panties To Be Stained Black In The Crotch Area?

I had a hysterectomy about 3 years ago and have been noticing all my panties are stained black in the crotch area. I have no discharge. In the morning I put on fresh ones after my shower and by the end of the day the stain is darker. What is causing this?

Hi,

Certain chemicals (HGA) in urine when stands mixed with sweat turns black to stain underwear black. Alkaline soap applied to it makes it more darker. It's supposed to be a normal phenomenon using cotton panties of dark color. Avoiding sweating, using the pantiliners are few things to help you.

Take care. Hope I have answered your question. Let me know if I can assist you further.
