Hi A. , sorry that you are going through this , I have the same problem , and I always thought it was kidney stone passing through my ureter the tube like tubes that run from your kidney's to the bladder and down to the uretha, and since ,I do suffer from kidney stones ,and I have passes some in the pass. Thats why I thought that my problem was kidney stone passing, Any how I found this wonderful urologist, after seeing like a hundred or so I also saw Gynecologist , you name it ,and no one could find out what was causing my pain . I have seen a lot of urologist in the pass until I found her , her name is Dr. Cercconie she is with the San Antonio Urology group . She suspected it to be something called Interstitial Cystitis ,IC for short, another way to name it is Painful Bladder Syndrome or Painful Pelvic Syndrome as well. While the exact cause is unknown, many experts believe that IC occurs when the mucous layer that lines and protects the bladder wall is damaged . This allows irritating substances in the urine to aggravate and inflame the bladder wall. , She will have to run a test first to determine if indeed that is what is causing your pain. The test is a little embarrassing , and a little uncomfortable but its not too bad , I had postpone the test at my first apt . for the test because I had heard of the test being really weird , but I am glad that now ,I finally know what my problem is , the bad thing about it is that there are no cures for this condition , and they really don't know what causes it , but there is some treatments to help you cope with the pain .My doctor is really good I am so impressed with her, after suffering for years and no one had found my problem until now . There also is a diet that you have to follow , in order to help you with your pain . You should try and see if this is your problem . Take care of yourself and God Bless , if you want to know what exactly does the test involve , you can email me private and I will be more than glad to give you detail by detail .Good luck and I hope you get better.
