I was sterilised about 5 months and when they went in they seen that my overy was dead. I was asked if I wanted it removed, which I declined, because I was getting over the sterilisation. I have read up on the symptoms and I have all of them. I thought I was starting early menopause and suffer from a bad back and never thought anything more about it. My question is, does the tube need removing and is it Dangerous left untreated ?
