I have had 5 surgeries in the past 7 months: 2 for colon cancer, 2 for cervical/uterine cancer (resulted in total hysterectomy), and one for a lumpectomy (small lump in breast/benign). I am tired all the time and have gained 20 lbs in the past month (after being put on Estradiol). I also am bloated, have stomach aches, joints ache, headaches, am dizzy at times, decreased libido, and intermittent blurred vision. I am thinking perhaps my Thyroid is off? What kind of test should I have run now? You would not believe the # of tests I have had in the last year alone but never any to do with my thyroid. Please help!
