I'm 8 days post surgery (full abdo surgery) to drain two cysts and treat endo. The couldn't remove the cysts as they are stuck to ovaries. Biopsy has been taken as one cyst is 'odd'. Now I've been put on Prostap and been told i might be on it for upto a year!! This will be my third time on this treatment and I know that it's supposed to last for 6 months max!! Has anyone else been on this treatment more than once??? I've had two other surgeries in 2008 and 2011 both laparoscopic. I'm 35 and have no kids. My endo is now classed as severe and that's within a 2 year span since last treatments, is this really worth it!??
