bel78.....i would be asking your gp to do an u/s to find out why you have the sever pain and heavy bleeding etc.....the u/s will also see if you have any lesions anywhere that shouldn't be there, any inflammed cysts near or around your clip sites.....it won't however show up the endo if you think you may have it, only surgery will show that.....i have had 2 surgeries so far for the endo and trust me this is something you don't want to have.....who are you planning to go see about a TR ?.....best of luck on your TR journey.....cheers kiya
