Women who go onto hormone replacement therapy (HRT) after endometriosis may find the drug reactivates the problem.
This happened to one 47 year old woman, even though she had a hysterectomy to treat the endometriosis.
She was put on a course of HRT but soon complained of kidney pains. Doctors discovered that the right kidney was obstructed, caused by a reoccurrence of endometriosis.
