Yeah - for me, Zoladex was a godsend - however it only helped ease my pain for half of the time so I would have 12 weekly injections - the first 6 weeks I felt brilliant, the last 6 weeks the pain started to return.
This meant that after my last injection 12 months ago I had 6 weeks good and then since then have gotten progressively worse. I felt really really bad for the first 2 months after I came off with terrible pains back etc, then it settled to a point where the pain was bad but managable, and the over the last 4 weeks I have been getting the worst I think I have ever been - to the point where at times I cannot stand up straight, walk, get into the bath, get into the shower, brush my own hair or even do the very slight twist you have to do to put your arms into your coat.
My endo is severe and it is all over my bowel as well, so I dont mean to scare you and you may find things are a lot better than I am describing - I am by no means the "norm" when it comes to endo, things always seem to be on the more severe end of the scale, but from personal experience, I would do all you can to stay on it as long as possible.
Also the LAST thing you want is to be on it, come off it and then get put on again because it just completely and totally wrecks your hormones. xx
