There are a number of problems that are very difficult to diagnose. I had endometriosis for seven years back in the dark ages before diagnosing this had improved. Finally the doctor did a hysterectomy that diagnosed the endometriosis and removed much of it. Later I had Interstitial Cystitis, also difficult to diagnose, for about as long as the endometriosis. Finally my doctor did a cystoscopy which indicated the IC and treatment was then started. Then I had vaginal atrophy which is fairly easy to diagnose and for which I am now on vaginal hormones. All of these are very painful and the IC pain did run down my leg. All of these in combination are called pelvic floor disorder. In addition to this, I now have colitis and a disfigured coccyx. Sometimes you just have to be very persistent to get to the bottom of problems. I was going to say patient but it is very difficult to be patient when you are in pain. And many of these are called silent diseases because on the surface you look fine. Stay strong.
