This is an often painful disorder whereby, the tissue that normally lines the inside of your uterus grows outside your uterus. It most commonly involves the ovaries, fallopian tubes and the tissue lining the pelvic region. I am talking about Endometriosis. How many of you have ever heard about it? If not, don’t you worry, I had never heard about it myself until my friend, a classmate in campus, shared her awful painful experience during her periods.
