Nas I think I mentioned my friend before. Two years waiting and she is still not allowed to start hrt as they don't want her two large fibroids to grow any bigger. Do you know how long until the hysterectomy? She also had a few rounds of the injections to try and shrink them before the op, both times her op was cancelled. Not trying to be a downer but I do think you need to push hard for timescales, play every card you've got, even if it means going for choose and book with a different Trust if you can find one with shorter waiting lists.
I am so glad, however, that you finally know what has been causing you all this pain and that you have a path out of there - now I just want that path to be clear and quick for you xxx
