Endo recurring 12 years after hysterectomy?

[Dido26]

Hi. I am new to this site as I haven't had any cause to stay in touch with other endo sufferers until now!! After years of suffering with endo a laparoscopy revealed that I was indeed covered in it and decided at 41 to have a total hysterectomy. I was the new put on HRT to counteract this. I have to say that after my initial recovery I then went on to have years pain free and was pleased that I had made that choice. I had my quality of life back. I am now 52 and for the past few weeks I have started to have those familiar symptoms I thought would never rear their heads again!! Has anyone else experienced similar circumstances? I am still on the HRT but am aware I should probably be thinking of reducing that in the very near future. I was told that if any tiny remains of the endo was left after surgery it could take years to grow again. Is this the case? I really would welcome any advice/help.
