Had zoladex last year for the first time and it worked brilliantly. I then had it again in January but with Livial, this time it didn't work. went back to gynae and he said it can't be endo if zoladex didn't work. Have had scans and blood tests to check for other things. I am convinced it is endo as it is the same pain I have always had and was treated for endo with laperoscopy 2 and half years ago. Just wanted to see if anyone else has had the same results. Due back to gynae in sept and need something to argue with as regards to diagnosis. Feeling totally fed up with it all now as been several years and technically still do not have a firm diagnosis. take 6 tramadol daily for pain but even that doesn't work now. Not ready for hysterectomy.
