I had lap in Oct and have severe endo that was treated at time. I've continued to have severe pain with each period. My consultant said to try zoladex and after a couple of wks thinking it over i had first injection on 15th march. I was very emotional when i decided to go through with it as I'm only 33. I just started my period yesterday and am in absolute agony. For the last 3 hrs I've been in unbearable pain can't even walk. I am normally in a lot of pain but things got worse after lap. i don't know if its just another bad month or zoladex injection. Has anyone else experienced this?
