When I was 18, 150lbs, a stone-like object a little less than the diameter of a quarter, and dark brown in color was discharged vaginally. I was sexually active and have never been diagnosed with an STD. I have never gotten an answer as to so much as a theory on what the cause could have been. I also experience constant vaginal discomfort. Not in the form of pain or itching but in a way I find difficult to describe. I have felt the same constant discomfort for years under my finger and toe nails as well as my stomach. I am now 26, 175lbs, since childhood I have had consistant complaints of constant nausia, headeach, bloating, abdominal cramping and shooting pain, diarrhea, constipation, and sensitivity to light and sound not always accompanying a headach. No doctor has given even a theory on what the cause may be.
