I have not felt good for a long while, I am very tired all the time, have painfull periods with heavy flowing. Recently I thought I was constipated after a week of laxatives and no result I went to the ER to have an X-ray I was not constipated but a Cat scanned showed 3 very large masses One near my pelvic, one close to my Kidney and the other one near my rectum. My White blood cell count was 17,000 which was high, what could theses masses be ?
