I thought you had to have gone through a pregnancy to have it so that it would fit coorectly? I had super sore breasts and lots of underarm pain. The doctor had me wait it out. It would come and go, but was horrible since I always thought about cancer. I ended up havind a mammogram and that looked fine, but have been so much happier with it out. I was not able to feel my strings because the doctor had cut them so short because my husband kept feeling them. I think it's horrible if you can't feel them though, because then how are you supposed to know if it's in the right spot? This was a horrible device for me with tons of symptoms. If I were you I would get it out now before it causes more problems.
