thermal endometrial ablation was a huge relief from excessive bleeding. But after one year of enjoying my life without periodsI began to have severe pain that landed me in the hospital, ultrasound showed a 5cm mass in uterin. whenblood flow would get cut off to the mass it would bring on severe pain. A hysterectomy was the only solution.findings were endometriosis ( that I never had prior to the ablation) It was determined that the ablation did not completely cover the lining of the uterus, where it missed continued to bleed and create a endometrial mass that brought the worst pain I have ever endured, including 4 natrural child births. Thanks for letting me share:)
