Did you ever find out what was wrong? I'm having the same problem, and the pressure did start right after I tried the Nuva ring (but after a day or two i didnt like it and took it out) I have been to multiple doctors and they are clueless to what is causing the problem...did you get any results to help me?! Thanks.
Thank you. I did try to find information on the internet and I am also a nurse. But so far I have not found much. Most all searches keep leading to cystocele/rectoceles, but I do not believe that is the problem. It feels similar to restless leg syndrome, but in my vagina. (sounds crazy, I know!) I never heard of anything like it before, but I will definitely see my doctor as soon as possible.
I wish I had an answer for you, but I don't. However, having said that, I really advise that you see a GYN Doctor asap. I'm not familiar with anything pertaining to the Nuva Ring so can't address that. Have you researched the Internet to see if problems of this nature have been reported? Regardless, this problem you are having is not normal and should be addressed by a medical professional. Good luck and hope you are feeling better soon.
p.s. I don't know that not having had a child makes any difference as far as pelvic problems go. My thought is that if you have one, (pelvis, kidney, etc), something can go wrong with it.
