I have been finding that when I wear white panties I am finding very light black marks on my panties. I had a total hysterectomy about 4 years ago to include my ovaries and Cervix. Did not need chemo. The only thing that is happening now is every once in a whild I am getting an ache in my pelvic area. I have made an appt for a cat scan of the area. Any suggestions? I am a 62 yo female.
