No. I am not even suggesting I have Chondrosarcoma.
Other than unexplained back pain in the area I read about (real severe at times), that come and goes, I am just looking for what others remembered early on before actually being diagnosed. I think if folks would keep notes of odd pain and etc, it might help doctors close in on the problem a bit sooner, providing the insurance companies let the doc's take the time and they want to do so, look at those notes.
The doctors think I have some sort of inflammatory arthritis (neck and parts of spine). I am just trying to help myself figure out other possible causes (if there are any), that are so far, only somewhat unexplainable.
