Well, I am back.
Just a month or so again, I decided to continue with the treatment, it had been a year. I called the doctor and the receptionist said he would get back to me soon, HAH, it took over 2 months. He decided to do another ultra sound as it had been so long and I had not had anymore new symptoms. I have not heard back on it, (it was a month ago already) but the tech said the endometrial thickness was less, it was 3 in thickness, and that mass was not any bigger. She said it looked very much like a "dermoid cyst" and it had probably been there a long time.
I now am waiting again to hear from the doc as to what to do next, I am glad that the wall was thinner and the "mass" no bigger, I feel all is well, but will be nice to hear from him about it. I hate all this waiting.
