Hi all. I'm 23 with endometriosis and polycystic ovaries. I had a laparoscopy last year however the pain returned so 3 and a half months ago I was given my first prostap injection. I have been struggling with the muscle aches and especially the mood swings. I feel so down and just burst into tears randomly. I'm due for my second injection in 2 weeks and I have heard that they sometimes offer hrt. Just wondering if having hrt helped anyone or did the side effects get worse .
