5 years ago i had a ruptured cyst that led the doctor to do a laparoscopy where they found i had stage 1 endo. Since then i've had a child, but now the doctor believes the endo has grown back. My periods have been painful and irregular (i'm on the pill). I've been bleeding for 2 weeks. Last week i had a vaginal ultrasound done and they found a cyst on my left ovary that is the size of an orange (6x4 sonograms). I go back next week in hopes that it decreased in size. My question is that the past few days i've had some dull pain on the left side including my back and leg. Sometimes the pains are sharp, but do go away. Are these symptoms that the cyst might rupture? Also, what are the chances that I will end up needing surgery? Any info on this will help!!! Thanks.
